The Stepper Board

This board is based on the DRV8825 Stepper Motor Driver. It works with standard x4 wire bipolar stepper motors.

Motor Voltage Supply from 8.2V to 45V
Phase Current up to 2.5A, but ~1A is more realistic without a heatsink and fan
Built in Step Controller, so strap the mode pins for the step mode: Full, Half, and Micro stepping.
Easy control from a Microcontroller, digital pins to set the direction, enable the part, and step the motor.
Fault Output Pin broken out and max current setting with a trim pot

 == Introduction ==
-Based on the low cost easy to use Real Time Clock IC MCP7940, this board offers a simple breakout for the part taking care of the sensitive crystal connections (probably wouldn't work very accurately on a breadboard).  The 'N' version is with a battery backup, where the 'M' is not.  Either part can be used.... if the N version is placed, then the board also provides a CR1220 battery holder, which should work with 12 or 12.5mm batteries.
