Open-source computing hardware are computer systems or elements with open design—designed as open-source hardware, using open-source principles.

Projects

The following is a list of open-source hardware projects that includes computer systems and components.

• Bug Labs – a handheld prototyping system based on the Texas Instruments OMAP3530 with ARM Cortex-A8 (600 MHz) and Angstrom Linux.
• Ethernut – open-source electronics prototyping platform for building tiny embedded Ethernet devices.
• Milkymist One – Single-board computer implementing all the core logic with open source Verilog HDL design files, which is confidential and proprietary in most other open-source hardware computers. It is an interactive VJ station featuring the open-source Milkymist SoC as CPU.
• Minimig – a re-implementation of an Amiga 500 using a field-programmable gate array (FPGA).
• Novena – a 1.2 GHz, Freescale quad-core ARM architecture computer closely coupled with a Xilinx FPGA by "Bunnie" Huang.
• Open Compute Project – for data centers by Facebook
• PLAICE – The PLAICE is an open-source hardware and software project developing a powerful in-circuit development tool that combines in one device the features of a FLASH Programmer, Memory Emulator, and High Speed Multi-Channel Logic Analyzer. It runs uClinux.
• PC532 – a personal computer design based on the NS32532 microprocessor, released in 1990.
• PULP – Parallel Ultra Low Power processing platform. Free and open-source implementations available from.
• Simputer – handheld computer aimed at developing countries
• Tinkerforge – Bricks and Bricklets (Modular hardware kit).
• Project Turris – open hardware and software WiFi and Ethernet routers, ready for hacking and tinkering. It runs an OpenWRT based OS

Boards

• Arduino — an open-source physical computing platform based on a simple I/O board and a development environment that implements the open source Processing / Wiring language. Also clones of this platform including Freeduino.
• Duino – Open-source hardware boards.
• Beagle Board – a single-board computer based on low-power Texas Instruments processors, using the ARM Cortex-A8 core, running Angstrom Linux.
• OLinuXino — an open-hardware single-board computer running Android (operating system) and Linux designed by OLIMEX Ltd in Bulgaria.
• Panda Board – a single-board computer forked from Beagle Board.
• Beagle Bone – Easy to extend Sitara ARM Cortex-A8 based boards, also from the Beagle Board family.
• Arm Pro Mini – is a small barebone open source ARM M0 microcontroller board
• IOIO – a board that allows Android applications to interface with external electronics
• IGEPv2 – an ARM OMAP3 based board designed and manufactured by ISEE in Spain. Its expansion boards are open-source hardware too.
• Banana Pi – Allwinner A20 based ARM boards made in China.
• MinnowBoard and MinnowBoard-Max – fanless Intel Atom based boards for embedded applications.
• Atmel SAMA5D3 Xplained and SAMA5D4 Xplained Ultra, boards based on an Atmel ARM Cortex A5 core. All design files seem to be available, but there is no explicit open-source hardware license statement.

CPU

There are several "open-source hardware" CPUs, typically implemented as a soft microprocessor.

• Amber is an ARM-compatible 32-bit RISC processor. Amber implements the ARMv2 instruction set.
• LEON is an open source 32-bit SPARC-like CPU created by the ESA. It's the standard CPU for the European Space Industry.
• Milkymist SoC, featuring the LatticeMico32 microprocessor core, has a complete set of independently developed open source system-on-chip cores such as a SDRAM controller, bus components, graphics accelerators and a variety of I/O devices.
• OpenCores is a loose community of designers that supports open-source cores (logic designs) for CPUs, peripherals and other devices. OpenCores maintains an open-source on-chip interconnection bus specification called Wishbone.
• OpenSPARC is an open-source processor project to which Sun Micro systems have contributed the Ultra SPARC T1 and Ultra SPARC T2 multicore processor designs.
• OpenRISC is a group of developers working to produce a very-high-performance open-source RISC CPU.
• RISC-V from University of California, Berkeley.
• ZPU is a small, portable CPU core with a GCC toolchain. It is designed to be compiled targeting FPGA.

Graphics cards

• Open Graphics Project aims to design an open architecture and standard for graphics cards.
• Milkymist SoC contains an open-source Verilog HDL design of an embedded high-performance 2D texture mapping unit.
• Nyuzi Processor – a GPL/LGPL-licensed GPGPU processor design. Nyuzi Processor is fully open-source with its Verilog, documentation, tests, compiler and tools.

Laptop case

• VIA OpenBook – A netbook case design released by VIA Technologies

Devices with casings

• Laptops:
  • Ben NanoNote – handheld notebook computer based on a MIPS processor running Linux.
• Smartphones:
  • Openmoko – a single-board computer (smartphone) with GSM/UMTS modem; GTA04 (ARM Cortex A8 with 1000 MHz) – old GTA02, with UPS battery.
  • Modular smartphone.

Wireless adapters

• Twibrigh RONJA, a 10 Mbit/s Full Duplex Free Space Optics wireless optical Ethernet adapter from 2001.
