Customer Comments

  • will the sparkfun AVR pocket programmer be able to program this board through the ICSP port?

  • There's no pull-up on the i2c clock (see schematic). You have to add one in yourself to get the eeprom working. Other than that, the board works great.
    I used it with ATMEGA16PU and 24LC256.
