ATmega & PIC Prototyping PCB

[Brendan]

I have built up some proto-PCBs with ATMega and Arduino bootloader. However, I have built some of these up with a 20Mhz resonator (25% faster than a "standard" Arduino)!

If you want to play with a 20Mhz Arduion, you'll need to add the following to your "boards.txt" in your Arduino folder.

Code:
