Portable stepper motor controller

This is a two channel version of a larger studio based stepper motor controller. The unit is portable and will be used for motion control applications outside the studio.

lid off- showing power supply, arduino and stepper drivers.  I use the Accelstepper library on the arduino to control the steppers.  Alternatively, for stop motion control I use Dragonframe which has a DFmoco sketch for the arduino..

User Manual for the stepper driver is here

The schematic I used (found on an animation motion control forum post) as a basis for the original 8 channel studio version is as below.  I just used 2 channels for the portable version.
