    If you leave out R2 and re-label CON PIN 1 from *PEN to PG5 you can use this board for the atmega2561 and atmega1281 processors as well as the atmega128 and atmega64.

      It should work fine.
      I have used a lot of these boards, and they are quite nice.

    Is it just me or are the JTAG pins missing?

    • Member #146685 / about 12 years ago / 1

      Yes, it seems like the picture is a prototype. Here is an image of the (green) version with the JTAG in place.

  • Don't suppose there is a chance you will be getting the microcontrollers to go with this board anytime soon?
