Replace ATSAMD21 With 20

HI all,

Is it possible to use the ATSAMD20G18 instead of the ATSAMD21G18 ?

I don’t need usb on my custom board, but I’ve developed all the code on the Zero (ATSAMD21G18),

Do I need to modify something? Bootloaders or other things if I export a the sketch bin file from the

Arduino IDE?

Thanks :slight_smile:
