Re draw of Tinhead's Valkyrie stepper motor board (V2.7)to use surface mount parts in a single sided board to make it easy to fabricate yourself.This uses I2C to communicate with the main board (see; http://letsmakerobots.com/node/9006)Because it is surface mount I added an isp header to allow programing and just for fun I added a ftdi header. I also added a second I2C header to allow easy daisy chaining of stepper boards.This is untested as of yet, so use at your own riskPlease note this is designed for all sockets and pin headers (basically all through hole parts) to be mounted from the BOTTOM side of the board (opposite the surface mount parts)
