Upgrading old Arduino boards ?

I have two older Arduino boards, from the first generation with USB.

Can i upgrade these boards by just replacing the Atmega8 processor with the 168 processor ?

If it is possible, do i need to make other changes to the board ?



yes you can. i did just replace the atmega8 with a 168 (that had the bootloader preburned though)…
set the right microcontroller target in the arduino software (168 instead of 8) and there you go.


I should not be too difficult to get the bootloader burnt on a 168. Or just by one already burnt.
I think i’m going to give it a try myself, because i’m thinking about a few projects where i want to develop something with the Arduino board, but use the Atmega168 “standalone” after initial development.
