Metaboard is a USB based prototyping board for Atmel's AVR microcontrollers. It is designed to be (mostly) compatible with Arduino. Its entire design (hardware and firmware) is Open Source.
Design Goals
- Low complexity and thus extremely low price.Single sided PCB so that the board can be manufactured at home. If professionally manufactured, a single sided board is still cheaper.No SMD components. Easy to assemble at ome.
- (Mostly) compatible with Arduino in board dimension and connector layout. Can also be programmed by Arduino's development environment via USB.
- No upfront investment for development environment or programmer hardware.
- Breadboard area on board.
- Completely Open Source.
Hardware
Since USB is implemented in firmware, no special USB driver chip is needed. Circuit diagram

The most recent version of Metaboard can always be obtained via SVN from.

Firmware
Metaboard is best used with Arduino. This is a boot loader which emulates USBasp, a USB based AVR programmer. The main firmware loaded with this boot loader is your business, of course.

Now the Metaboard in our shop is with bootloader and assembled solder.
