List of open-source hardware

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.^[1]^[2]^[3]
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.
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 ^[4]

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 is 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
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.
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.

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.
The ZPU is a small, portable CPU core with a GCC toolchain. It is designed to be compiled targeting FPGA.^[5]

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 - an GPL/LGPL-licensed GPGPU processor design. Nyuzi Processor is fully open-source with its Verilog, documentation, tests, compiler and tools.^[6]

Laptops:
