MotoMama is a Arduino shield based on L298N H-bridge driver chip.
You can use this shield to drive two DC motors or an four-wire two-phase stepper motor. For power supply , power terminal on board is available – it will also power the Arduino board. Or from the power jack on Arduino board, the shield will get the power form the Vin pin of Arduino and derive the motor using this power.
In many motor and robot project, you need to use the wireless communication, so on board we build a wireless area. Now you can directly put a XBee (or other XBee pins compatible module, like BTBee) and a nRF24l01 module on the board.
We layout the reset pins which not be used for LN298 and wireless on board, and they are all the AD pins of arduino, so you can use this pins as the sensor input or output.
We hope this design can be used as the motherboard of many small motor or robot project, because it has enough resources for wireless communication, sensor data acquisition and some simple control, so we name it “MotoMama” : ) , not Motorola.
MotoMama not only can be used as a Arduino UNO or IFLAT shield, but also can be used as a DC driver platform, so we didn't emsamble the pins on board, so that it will have more applicability - using the positioning hold on board, you can fix it on your robot chasis.

I have a lot of experience with stepper motors, but I have been unable to get one working with this board. Has anyone out there got this to work? I am using a standard 4 wire stepper. I wired one coil between OUT1 &2 and the other between OUT3 & 4, with 12V fed to VSUPPLY and GND. The supplied program doesn't work. I soldered headers to the board and plugged it into my ITEADUINO. I must be missing something fundamental.
