  • 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. http://www.shop.kristech.eu/product_info.php?cPath=22_38&products_id=55&language=EN
