Raspberry Pi

Origins and launch (2008–2012)

The Raspberry Pi Foundation was established in 2008 by a group including Eben Upton, in response to a noticeable decline in both the number and skill level of students applying to study computer science at the University of Cambridge Computer Laboratory. The foundation's goal was to create a low-cost computer to help rekindle interest in programming among schoolchildren.[1][2][3]

This mission was inspired by the aims of the BBC Micro computer of the early 1980s, which was developed by Acorn Computers as part of a BBC initiative to promote computer literacy in UK schools.[4] The names "Model A" and "Model B" were chosen as a deliberate homage to the BBC Micro.[5] The name "Raspberry Pi" combines the fruit-themed naming convention used by early computer companies with a nod to the Python programming language.[6]

The first prototypes resembled small USB sticks.[7] By August 2011, fifty functionally complete "alpha" boards were produced for testing,[8] with demonstrations showing them running a Debian-based desktop and handling 1080p video playback.[9][10] In late 2011, twenty-five "beta" boards were finalized,[11][12][13] and to generate publicity before the official launch, ten of these were auctioned on eBay in early 2012.[14][15]

The first commercial Raspberry Pi, the Model B, was launched on 29 February 2012, with an initial price of $35. Demand far exceeded expectations, causing the websites of the two initial licensed distributors, Premier Farnell and RS Components, to crash from high traffic.[16][17][18] Initial batches sold out almost immediately, with one distributor reporting over 100,000 pre-orders on the first day. The lower-cost $25 Model A followed on 4 February 2013.[19]

The Raspberry Pi did not ship with a pre-installed operating system. While ports of RISC OS 5 and Fedora Linux were available,[20][21][22] a port of Debian called Raspbian quickly became the standard. Released in July 2012, it was optimized to leverage the Raspberry Pi's floating-point unit, offering significant performance gains.[23][24] Raspberry Pi quickly endorsed it as the official recommended OS, and by September 2013, the company assumed leadership of Raspbian's development.[25]

Corporate evolution

In 2012, the Foundation restructured, creating Raspberry Pi (Trading) Ltd. to handle engineering and commercial activities, with Eben Upton as its CEO.[26] This allowed the Raspberry Pi Foundation to focus solely on its charitable and educational mission. Raspberry Pi (Trading) Ltd. was renamed Raspberry Pi Ltd. in 2021.[27] In June 2024, the company went public on the London Stock Exchange under the ticker symbol RPI, becoming Raspberry Pi Holdings.[28][29][30][31]

Post-launch production (2012–2014)

Following the launch, the first units reached buyers in April 2012.[32] To address overwhelming demand and initial supply chain issues, the Foundation ramped up production to 4,000 units per day by July.[33][34] The first batch of 10,000 boards was produced in factories located in Taiwan and China.[35][36] A significant strategic shift occurred in September 2012, when manufacturing began moving to a Sony factory in Pencoed, Wales.[37][38] During this period, the hardware was also refined: the Model B Revision 2.0 board was announced with minor corrections, and in October, its included RAM was doubled to 512 MB.[39][40][41]

The post-launch period focused heavily on software and ecosystem development. In August 2012, the Foundation enabled hardware-accelerated H.264 video encoding and began selling licenses for MPEG-2 and VC-1 codecs.[42][43] A major milestone for the open-source community occurred in October 2012, when the Foundation released the Videocore IV graphics driver as free software. While the claim of it being the first fully open-source ARM SoC driver was debated, the move was widely praised. This effort culminated in February 2014 with the release of full documentation for the graphics core and a complete source release of the graphics stack under a 3-clause BSD license.[44]

Product line expansion (2014–present)

In 2014, the Raspberry Pi product line began to diversify. April saw the release of the Compute Module, a miniature Raspberry Pi in a small form factor designed for industrial and embedded applications, which would soon become the largest market for the computers. In July the Model B+ was released with a refined design featuring additional USB ports and a more efficient board layout that established the form factor for future models.[45][46] A smaller, cheaper ($20) Model A+ was released in November.[47] A significant leap in performance came in February 2015 with the Raspberry Pi 2, which featured a 900 MHz quad-core CPU and 1 GB of RAM.[48] Following its release, the price of the Model B+ was lowered to $25, a move some observers linked to the emergence of lower-priced competitors.[49][50]

The Raspberry Pi Zero, launched in November 2015, radically redefined the entry point for computing at a price of just $5.[51] In February 2016, the Raspberry Pi 3 marked another major milestone by integrating a 64-bit processor, Wi-Fi, and Bluetooth. The product line continued to expand with the wireless-enabled Raspberry Pi Zero W (February 2017),[52][53] the faster Raspberry Pi 3B+ (March 2018),[54] Raspberry Pi 3A+ (November 2018),[55] and Compute Module 3+ (January 2019).[56]

The Raspberry Pi 4, launched in June 2019, represented another major performance leap with a faster processor, up to 8 GB of RAM, dual-monitor support, and USB 3.0 ports. A compute module version (CM4) launched in October 2020.[57] This era saw further diversification with the Raspberry Pi 400 (a computer integrated into a keyboard) in November 2020,[58] and the Raspberry Pi Pico in January 2021. The Pico, based on the in-house designed RP2040 chip, marked the company's first entry into the low-cost microcontroller market. The Raspberry Pi Zero 2 W, introduced in 2021, featured a faster processor, providing a significant performance boost while maintaining the low-cost, compact form factor.

The global chip shortage starting in 2020, as well as an uptake in demand starting in early 2021, notably affected the Raspberry Pi, causing significant availability issues from that time onward.[59] The company explained its approach to the shortages in 2021,[60] and April 2022,[61] explaining that it was prioritising business and industrial customers.

The Raspberry Pi 5 was released in October 2023, featuring an upgraded CPU and GPU, up to 16 GB of RAM, a PCIe interface for fast peripherals and an in-house designed southbridge chip.[62] Updated versions of the Compute Module (CM5) and keyboard computer (Pi 500, Pi 500+) based on the Pi 5's architecture were subsequently announced. The Raspberry Pi Pico 2, released in 2024, introduced the RP2350 microcontroller, featuring selectable dual-core 32-bit ARM Cortex-M33 or RISC-V processors, 520 KB of RAM, and 4 MB of flash memory.

Raspberry Pi expanded its artificial intelligence focused hardware ecosystem with the release of the Raspberry Pi AI Camera, based on Sony's IMX500 Intelligent Vision Sensor. The product integrated on-sensor neural network inference, enabling edge-based computer vision applications when paired with Raspberry Pi computers. The company also introduced the Raspberry Pi AI HAT+, incorporating a Hailo neural processing unit (NPU) to accelerate machine learning workloads on the Raspberry Pi 5 platform. The accessory was positioned for high-performance edge inference use cases, including industrial automation and embedded AI systems.[63]

During the same period, Raspberry Pi announced updated keyboard-integrated desktop models derived from the Raspberry Pi 5 architecture. These revisions included expanded memory configurations and enhanced storage options, continuing the company's development of compact, integrated desktop computing systems.[64]

Sales milestones

The Raspberry Pi's sales demonstrated remarkable growth. The one-millionth Pi was sold by October 2013,[65] a figure that doubled just a month later.[66] By February 2016, sales reached eight million units, surpassing the ZX Spectrum as the best-selling British computer of all time.[67] Sales hit ten million in September 2016,[68] thirty million by December 2019,[69] and forty million by May 2021.[70] As of its tenth anniversary in February 2022, a total of 46 million Raspberry Pis had been sold.[71] As of March 2025, 68 million units had been sold.[72]

Model/series comparison table

Notes

Processors and system on chip

Raspberry Pi models use a range of system on a chip (SoC) designs, developed in partnership with Arm and Broadcom. Each generation has introduced improvements in CPU architecture, clock speed, graphics, and overall performance.

The original Raspberry Pi and the Pi Zero use the Broadcom BCM2835, featuring a single-core 32-bit ARM11 CPU and a VideoCore IV GPU. The CPU is clocked at 700 MHz on the original Pi and 1 GHz on the Zero and Zero W.[102][103]

The Raspberry Pi 2 introduced the BCM2836 with a 900 MHz quad-core 32-bit Cortex-A7 CPU,[104] while later revisions used the 64-bit BCM2837 with Cortex-A53 cores.[105] The Raspberry Pi 3 retained the BCM2837, increasing the CPU clock to 1.2–1.4 GHz depending on the model.[106][107][108] The Pi Zero 2 uses the RP3A0, a system in a package (SiP) combining the quad-core Cortex-A53 processor clocked at 1 GHz with 512 MB of RAM.[109][110]

The Raspberry Pi 4 introduced the BCM2711, a 64-bit SoC with a quad-core Cortex-A72 CPU and VideoCore VI GPU. Clock speeds were initially 1.5 GHz and later increased to 1.8 GHz.[111][112][113][114] The Raspberry Pi 5 uses the BCM2712, featuring a quad-core Cortex-A76 CPU at 2.4 GHz, an 800 MHz VideoCore VII GPU, and a separate RP1 southbridge chip designed in-house.[115]

Raspberry Pi has also developed its own chips outside of its partnership with Broadcom. The Raspberry Pi Pico uses the RP2040, featuring dual-core 32-bit Cortex-M0+ processors running at 133 MHz and 264 kB of on-chip RAM.[116][117] The Pico 2 uses the RP2350, which can operate with either dual-core Cortex-M33 or dual-core Hazard3 RISC-V CPUs selected at boot, running at 150 MHz, with 520 kB of RAM.[118][119]

Overclocking

Most Raspberry Pi models support user-configurable overclocking through the system configuration file. More recent models feature dynamic frequency scaling, adjusting CPU speed based on workload to balance performance and thermal output. This behavior, while similar to overclocking, is part of the default power management system. If the CPU temperature exceeds 85 C or if undervoltage is detected, performance is throttled automatically. For sustained high-performance workloads, additional cooling—such as a heat sink or fan—may be required.[120][121]

RAM

The original Raspberry Pi Model B was equipped with 512 MB of random-access memory (RAM), which, like later models, shares memory between the CPU and GPU. All Raspberry Pi boards support dynamic memory allocation between these components, allowing the system to adjust the division based on workload or user configuration.[122] The original Model A included 256 MB of RAM.

Subsequent models introduced increased memory capacities. The Pi 2B and 3 B/B+ models feature 1 GB of RAM, while the smaller 1A+ and 3A+ models have 512 MB. The Pi Zero and Zero 2 W also include 512 MB. The Pi 4 is available with 1, 2, 3, 4, or 8 GB of RAM,[76] and the Pi 5 expands this further with options for 1, 2, 4, 8, or 16 GB of RAM, the highest capacity offered to date.[123]

On 1 April 2026, Raspberry Pi announced a 3 GB version of the Raspberry Pi 4 due to the increasing cost of LPDDR4 RAM. The PCB was redesigned to use two 1.5 GB chips, which are cheaper and in greater supply.[76][124]

Storage and peripherals

Storage is typically provided via a microSD card, though some Compute Modules offer onboard eMMC flash.[125] Newer models support USB booting, and the Pi 5 includes support for NVMe SSDs over PCIe. The original Model A and Model B uses a full-sized SD card slot.[126]

Boards also include USB ports for peripherals such as keyboards, mice, and storage devices.[127][128]

Video

Raspberry Pi devices support both digital and analog video output across various resolutions.

Early models featured a full-size HDMI port and an RCA connector for analog composite video output. Later boards removed the RCA jack but retained analog output via the 3.5 mm TRRS jack or dedicated solder points. According to the Raspberry Pi Foundation, analog support helps maintain accessibility in developing countries.

To accommodate the addition of features on the compact boards, video connectors have shrunk across models. The Pi Zero series uses a mini-HDMI connector, while the Pi 4 and 5 use dual micro-HDMI ports. This change enables support for multiple displays: the Pi 4 can drive two 4K displays at 30 Hz or one at 60 Hz, while the Pi 5 improves on this with support for two 4K displays at 60 Hz.[129]

Older Raspberry Pi models support common display resolutions such as 720p and 1080p by default, with some capable of higher resolutions depending on hardware and configuration. In some cases, older hardware can output in 4K, though performance may be poor.[130][131]

GPIO header

Most Raspberry Pi models include a 40-pin connector known as the GPIO (general-purpose input/output) header, although only some of the pins are dedicated to GPIO functions. The header, designated as J8, uses a consistent pinout across models.

The header supplies 3.3 V and 5 V power along with various multiplexed, low-speed interfaces, including UART, SPI, I²C, I²S, and PCM. GPIO pins can be configured as either inputs or outputs. When set as an output, a pin can drive a high (3.3 V) or low (0 V) signal. When configured as an input, it can read a high (3.3 V) or low (0 V) voltage level.[132]

The original Raspberry Pi 1 Model A and B include only the first 26 pins of this header.[133][134][135] On some Pi Zero models, the header is unpopulated, but solderable through-holes are provided. The Pico models feature a unique layout with unpopulated through-holes and a castellated edge, allowing it to be surface-mounted as a module. Compute Module boards do not include GPIO headers but instead expose GPIO signals through their board connectors.

Networking

Networking capabilities differ by model. The Model B and B+ include an Ethernet port. Starting with the Raspberry Pi 3, most models come with built-in WiFi and Bluetooth. The Raspberry Pi 3B+ adds faster Ethernet and dual-band WiFi. The Raspberry Pi 4 and 5 offer full gigabit Ethernet. The "A" models and the Pi Zero series do not have Ethernet ports, and built-in wireless support is optional. A USB adapter may be used for wired or wireless connections. Headless Raspberry Pi configurations may experience intermittent network connectivity issues, often attributed to default WiFi power management settings. These issues are typically addressable through configuration changes.

Special-purpose features

Some Raspberry Pi models, like the Zero, 1A, 3A+, and 4, can act like a USB device (via the USB On-The-Go protocol) when plugged into another computer.[136] This lets them work as gadgets such as a virtual keyboard, network adapter, or serial device.[137]

Many newer models can also start up (or "boot") directly from a USB drive, without needing a microSD card. This feature is not available on older models like the original Raspberry Pi, Pi Zero, or early versions of the Pi 2.[138]

Real-time clock

Most Raspberry Pi models do not include a built-in real-time clock, which means they rely on an internet connection to set the correct time with the Network Time Protocol when they start up. If there is no connection, the time must be set manually; otherwise, the system assumes no time has passed since it was last used. Add-on clock modules are available for situations where accurate timekeeping is needed without internet access.[139][140] The Raspberry Pi 5 is the first model to include a built-in clock which uses a battery to keep time when powered off.[141]

Board layouts

Operating systems

The recommended operating system is Raspberry Pi OS, a Debian-based Linux distribution optimized for Raspberry Pi hardware and tuned to have low base memory requirements. It is available in both 32-bit and 64-bit versions and comes in several editions: a standard edition, a "Lite" version without a desktop environment, and a "Full" version that includes a comprehensive suite of software.

Raspberry Pi OS can be purchased pre-installed on a microSD card,[235] or downloaded and installed using Raspberry Pi Imager, a utility introduced in March 2020 to simplify the installation of operating systems onto SD cards and other media for Raspberry Pi devices. Available for macOS, Raspberry Pi OS, Ubuntu, and Windows, Imager allows users to download and write operating system disk images within a single application.[236] In addition to Raspberry Pi OS, the utility supports a variety of third-party operating systems, including Alpine Linux,[237] Armbian,[238] Emteria.OS (Android based),[239] FreedomBox,[240] Kali Linux,[241] LibreELEC,[242] RetroPie,[243] RISC OS,[244] SatNOGS,[245] and Ubuntu.

Firmware

The Raspberry Pi uses official firmware that is proprietary, meaning its source code is not publicly available, but the binary blob can be freely redistributed.[246][247] An experimental open-source alternative to the official firmware is also available. Although limited in functionality, it demonstrates that it is possible to start the Raspberry Pi's ARM processor cores and boot a basic version of the Linux kernel without relying on the proprietary components. This is significant for developers and advocates who aim to build fully open systems.[248]

Driver APIs

Raspberry Pi systems use Broadcom's VideoCore GPU, which requires a proprietary firmware binary blob to be loaded at boot. Initially, the supporting software stack was entirely proprietary,[249] though parts of the code were later released. Most driver functionality remains within the proprietary GPU firmware, accessed via closed-source runtime libraries such as OpenMAX IL, OpenGL ES, and OpenVG. These libraries interface with a kernel-space open-source driver, which in turn communicates with the proprietary GPU firmware. Applications use OpenMAX IL for video, OpenGL ES for 3D graphics, and OpenVG for 2D graphics, with all graphics libraries making use of the closed-source EGL interface.[250]

In February 2020, Raspberry Pi announced the development of a Vulkan graphics driver.[251] A working prototype demonstrated high performance in Quake III Arena on a Raspberry Pi 3B+ later that year.[252] On 24 November 2020, Raspberry Pi 4's Vulkan driver was declared conformant.[253]

Debugging and utility

• Debug probe (2022) – RP2040-based hardware debug tool for Raspberry Pi and RP2040 development boards.
• RTC battery (2024) – Rechargeable lithium battery for powering the real-time clock on Raspberry Pi 5 during power loss.

Community

The Raspberry Pi community was described by Jamie Ayre of FOSS software company AdaCore as one of the most exciting parts of the project. Community blogger Russell Davis said that the community strength allows the Foundation to concentrate on documentation and teaching. The community developed a fanzine around the platform called The MagPi[288] which in 2015, was handed over to Raspberry Pi (Trading) Ltd by its volunteers to be continued in-house.[289] A series of community Raspberry Jam events have been held across the UK and around the world.[290]

Education

As of, enquiries about the board in the United Kingdom have been received from schools in both the state and private sectors, with around five times as much interest from the latter. It is hoped that businesses will sponsor purchases for less advantaged schools.[291] The CEO of Premier Farnell said that the government of a country in the Middle East has expressed interest in providing a board to every schoolgirl, to enhance her employment prospects.[292][293]

In 2014, the Raspberry Pi Foundation hired a number of its community members including ex-teachers and software developers to launch a set of free learning resources for its website.[294] The Foundation also started a teacher training course called Picademy with the aim of helping teachers prepare for teaching the new computing curriculum using the Raspberry Pi in the classroom.[295]

In 2018, NASA launched the JPL Open Source Rover Project,[296] which is a scaled down version of Curiosity rover and uses a Raspberry Pi as the control module, to encourage students and hobbyists to get involved in mechanical, software, electronics, and robotics engineering.[297]

Home automation

There are a number of developers and applications that are using the Raspberry Pi for home automation. These programmers are making an effort to modify the Raspberry Pi into a cost-affordable solution in energy monitoring and power consumption. Because of the relatively low cost of the Raspberry Pi, this has become a popular and economical alternative to the more expensive commercial solutions.

Industrial automation

In June 2014, Polish industrial automation manufacturer TECHBASE released ModBerry, an industrial computer based on the Raspberry Pi Compute Module. The device has a number of interfaces, most notably RS-485/232 serial ports, digital and analogue inputs/outputs, CAN and economical 1-Wire buses, all of which are widely used in the automation industry. The design allows the use of the Compute Module in harsh industrial environments, leading to the conclusion that the Raspberry Pi is no longer limited to home and science projects, but can be widely used as an Industrial IoT solution and achieve goals of Industry 4.0.[298]

In March 2018, SUSE announced commercial support for SUSE Linux Enterprise on the Raspberry Pi 3 Model B to support a number of undisclosed customers implementing industrial monitoring with the Raspberry Pi.[299]

In January 2021, TECHBASE announced a Raspberry Pi Compute Module 4 cluster for AI accelerator, routing and file server use. The device contains one or more standard Raspberry Pi Compute Module 4s in an industrial DIN rail housing, with some versions containing one or more Coral Edge tensor processing units.[300]

Commercial products

The Organelle is a portable synthesiser, a sampler, a sequencer, and an effects processor designed and assembled by Critter & Guitari. It incorporates a Raspberry Pi computer module running Linux.[301]

Slice is a digital media player which also uses a Compute Module as its heart. It was crowd-funded in an August 2014 Kickstarter campaign. The software running on Slice is based on Kodi.[302]

Numerous commercial thin client computer terminals use the Raspberry Pi.[303]

COVID-19 pandemic

During the COVID-19 pandemic, demand increased primarily due to the increase in remote work, but also because of the use of many Raspberry Pi Zeros in ventilators for COVID-19 patients in countries such as Colombia,[304] which were used to combat strain on the healthcare system. In March 2020, Raspberry Pi sales reached 640,000 units, the second largest month of sales in the company's history.[305]

Military

The Iranian Geran-5 aerial drone is reportedly built around a Raspberry Pi.[306]

In space

A project was launched in December 2014 at an event held by the UK Space Agency. The Astro Pi was an augmented Raspberry Pi that included a sensor hat with a visible light or infrared camera. The Astro Pi competition, called Principia, was officially opened in January and was opened to all primary and secondary school aged children who were residents of the United Kingdom. During his mission, British ESA astronaut Tim Peake deployed the computers on board the International Space Station.[307] He loaded the winning code while in orbit, collected the data generated and then sent this to Earth where it was distributed to the winning teams. Covered themes during the competition included spacecraft sensors, satellite imaging, space measurements, data fusion and space radiation.

The organisations involved in the Astro Pi competition include the UK Space Agency, UKspace, Raspberry Pi, ESERO-UK and ESA.

In 2017, the European Space Agency ran another competition open to all students in the European Union called Proxima. The winning programs were run on the ISS by Thomas Pesquet, a French astronaut.[308] In December 2021, the Dragon 2 spacecraft launched by NASA had a pair of Astro Pi in it.[309]
