Note: This didn't go neither into testing nor production because of the use of microstepping drivers in the future.

This is a fork of the reprap stepper motor driver 2.3-r1. Changes include:
- Reduced size
- changed 5V voltage regulator to µA 78L05
- changed 5V voltage regulator to TO-92 package (cheaper).
- changed 100uF capicators to through-hole components (easier to solder)
