AVR boards for Arduino
This is a list of cpus/boards that I have made the Arduino environment work on.

"TESTED" means that I have that board and can make the Arduino software work on it.

Boards that are not "tested" will probably work, I just dont have one of them. My test code compiles properly for them.

NOTE: Some boards such as the attiny series do not work with bootloader support but can be used with ISP programmer.
