Motherboards that run Linux
Elphel cameras are free software and open hardware cameras. The cameras run Linux. The cameras have several interfaces -- 10/100 Ethernet, USB, IDE, RS-232, etc. It uses a FPGA for video processing and video compression. More information here at Open Circuits: Elphel camera; and at the Elphel wiki.
An ARM920T board running Linux at 200 Mips with sound, Ethernet, CAN, 48+ bidirectionnal IOs and 4 DSPs for motor control (DC, Servos, etc...). Built as a student proof robotics design platform.
The Bifferboard has:
- 150MHz CPU, Intel 486SX instruction set, MMU.

- 68mm x 28mm x 21mm (weight 28g)
- 32MB SDRAM/8MB Flash
- OHCI/EHCI USB 2.0
- 10/100 ethernet
- Serial console 115200 baud (can be used as 2 GPIO)
- 4-pin JTAG (can be used as GPIO)
- 2 permanent GPIO (1 LED, 1 button)
The Balloon project has produced Balloon3, a high-performance ARM board designed for use by OEMs and Higher education. Spec is PXA270 (583Mhz), FPGA or CPLD, 1GB flash, 784MB RAM, USB (master, slave, OTG), CF slot, expansion bus, 16-bit bus, I2C, LCD, serial, audio. Very low power in CPLD confiuguration. Small, light. Various add-on boards: VGA LCD driver, robot motor driver+A/D, digital IO. Released under the Balloon Open Hardware license, which allows anyone to manufacture and for people to make derivatives. The expansion bus allows balloon to be used as the computing component for various special-purpose devices.
- "Aleph One is shipping a one-ounce, one-watt, 206MHz StrongARM-based single-board computer (SBC) that comes pre-installed with embedded Linux and features an "open source" hardware design." 2004.
The linuxstamp is an open source processor module. It is designed to be a very simple board capable of running linux. It is based on the Atmel AT91RM9200 processor (An ARM9 processor with a MMU).
This is the first mother board for the linuxstamp. It is still in the planning stages (no pcbs).
The Linuxstamp II is an open source processor module. It is designed to be a very simple board capable of running linux. It is based on the Atmel AT91SAM9260 processor (An ARM9 processor with a MMU).
Motherboard for the Linuxstamp II to interface with RC servos.

LART -- an open license StrongARM based tiny SBC.
"All CAD files required for building LART are available under the closest we could get to an Open/Free Hardware License." The link in the Linux Devices article no longer works; the most recent link is http://www.lartmaker.nl/ . 75 mm x 100 mm.
- "Tiny "open hardware" SBC now available commercially": "Aleph One Ltd and Remote12 ... announce that they are able to supply LART boards, with a User Guide, software and cables." 2001.
- "Open hardware for open software" "Aleph One Ltd of Cambridge, England and Remote 12 Systems Ltd of London, England are now able to supply both LART and KSB boards, plus a User Guide, software, and cables." 2001. "The KSB board plugs onto LART and provides: IDE/ATA interface (44 pins on 2mm centers); stereo 16-bit 44KHz audio output at line and headphone levels; PS/2 connections for mouse and keyboard; mono audio I/O, POTS and ADC fron a UCB 1200chip; connectors for IrDA, USB Client, video, and touchscreen."
- "More LART SBCs?" 2002.
A Gumstix motherboard is called a COM, which stands for computer-on-module. Gumstix COMs are inexpensive, and have RAM/Flash, 802.11b/g, Bluetooth and power management "on COM". Each COM connects to a wide variety of openly published expansion boards that include USB interface (gadget mode and host mode) and have things like Ethernet, GPIO and LCD module interface.
An Overo COM is powered by a Texas Instruments ARM-based Stellaris, DaVinci or OMAP 35xx processor. A Verdex Pro COM is driven by a Marvel PXA270 (Verdex Pro series).
Very cool site.
All expansion boards are open hardware.
The Raspberry Pi is a low-cost (USD $35; GBP ~£22) credit-card sized Linux computer for teaching computer programming to children.
The same system sofware (Linux and mostly open-source software) runs on a very similar "Chumby Hacker Board" available from adafruit.
The Chumby wiki discusses the Chumby from chumby.com, the CHB from adafruit, and a few other closely related devices.
