Hi
I purchased one of these controllers on ebay. I found a similar product that had some arduino code that allowed me to get motors running.

Here is a copy of the code.
Cheers

NOTE:
motor.begin() will change the prescaller of the timer0,

Please use motor_delay(), motor_millis(), motor_micros() instead them.
