Green Boards Comin Outa Ma Ears

All my Drawbot boards arrived from the fabricator today.  Time to go by a bigger magnifier and get to building!

This is the communications board that converts USB to RS-485.

This is the board for the pen carrier.  It takes RS-485 in, and drives a servo to accomplish the pen up/down.

And this is the winch board.  It takes RS-485 in, and drives a 2 phase bi-polar stepper motor.
