Customer Comments

  • 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.

  • I got atmega128L 8ai 0608 microcontroller, wil this work for my microcontroller? guys this is my first project so please help me.

  • Is it just me or are the JTAG pins missing?

    • 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?
