I'm a software guy that has found learning and playing with microcontrollers as a fun way to get introduced to hardware/electronics. I've finished a cool little robot with AVR now working on something else I wanted to learn interfacing USB.
I wana fallow the schematic pictured below but I'm having a hard time figuring out what AVR they are using. I have a few spare atmega8-16PU laying around I'd love to use but I can't tell if its the one being used on this schematic. They use a chip that uses 3.3V and can go 16MHz. The atmega8L can't got 16MHz, and the regular atmega8 are 4.5-5V so I'm a bit confused whats going on :P
Someone mind telling me whats the 16PU part stands for btw?
