I started designing this controller in December 2011. After 4 months and 2 previous revisions it will finally be shipping out April 2012. I think this is DAGU's best Arduino compatible robot controller yet!
Designed for small robots using small batteries, the Micro Magician is a 3.3V controller running at 8MHz.
Working from 4.5V to 9V means this constroller can run from a single LiPo cell or 3x NiMh batteries.
Reverse polarity protection means no blue smoke if you get your power wires crossed (reverse polarity diode rated at 3A).
