Digital IO board

This board holds three AVR processors ATmega168 and implements 60 digital TTL level IOs that interface directly to the panel electronics. The digital outputs can lock and unlock turnouts and signals. The inputs are used to get feedback of turnouts and user requests for routes. Additionally the board implements SPI busses to connect train number displays. The design can be found on this page.
