I need to drive 4 ~2 amps DC motors with my Handy Board (which only delivers 1 amp max). I saw this post on the Handy Board FAQ page:
check out the motor drivers at pololu.com: pololu.com/catalog/category/11 These can wire into the L + R, on/off, and PWM outputs from the Handy Board (i.e., the inputs to the L293). So you can yank a 293 and run its signals to one of these board.
What does this mean? How can I interface a motor driver with my Handy Board?
