The NGW100 is a quite cheap (~100USD, 50 for students) development kit for the AVR32 processor.


  • AT32AP700x CPU, 140Mhz
  • Input Voltage 9-15V
  • SD/MMC Cardreader
  • 2x Ethernet
  • 1x RS232
  • 3x Expansion Headers
  • Device USB (offers access to the sdcard)
  • 32MB Ram

Through the expansion headers it is possible to attach an lcd display to it, as well as ps/2 keyboard.

It uses U-Boot as a bootloader.

Buildroot offers out-of-the box support for this board.
