a motor shield for an Arduino mega. It can drive 12 servo motors and 8 DC motors or 4 stepper motors at, full, 1/2 and 1/4 stepping.
The motor drivers used are found here: http://search.digikey.com/ca/en/products/A3988SEVTR-T/620-1176-1-ND/1232802 They only come in a 32-QFN package so they are impossible to solder without a hot air gun or solder re-flow oven.
This is an early version and there are still some bugs to work out in the library (not done yet so I haven't uploaded it) as well as the design.
