So, you get instructions in 5 ns, plenty fast for most step generation, PWM and such tasks. (There are actually TWO of these microcontrollers, but I think they only support one at the moment.) The CRAMPS board (don't really care for the name!) holds up to 6 Pololu-style step drivers plus a lot of other useful I/O. I run it over Ethernet, you can also connect to it with IP over USB.
