Metaboard for AVR

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.

Main design goals:

  • Low complexity and thus extremely low price.
  • Single sided PCB so that the board can be manufactured at home.
  • No SMD components. Easy to assemble at home.
  • (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.

USB is implemented in firmware, no special USB driver chip is needed.
