Use a DC motor with this driver or get stepper driver like this one http://www.sparkfun.com/products/10267
This little board worked a charm when using a 7.4v LiPo. Be careful when supplying more than 12 volts. When I supplied 14.8v the 47uF capacitor (C8) exploded. It’s probably a max 16v capacitor.
Also notice that the L298 on the board has no heat sink. It gets smoking hot when driving an RC car motor. I confess removing the overcurrent protection from the firmware.
My conclusion, great little board. My suggestions to SF for a new version of the board are obvious, replace the capacitor and use a L298 with heatsink.
No public wish lists :(
