Hey there everyone, my question is pretty simple.
I made a keyboard that can be reprogrammed using the serial COM Port using the ATMEGA32U4 3.3V 8MHz. Link : Amazon link
I am looking to make 20 of these keyboards, I went to BangGood.com and Found this one for 5$. it's a 5V 16MHz. Will I have trouble inserting my existing code inside the new board or do you think it'll work right away ? BangGood link
