Features
Based on the Freescale MC33932 dual H-Bridge Power IC
Lets you drive two DC motors with your Arduino/Seeeduino board controlling the speed and direction of each one independently
Output short-circuit protection (short to VPWR or GND)
Over-current limiting (regulation) via internal constant-off-time PWM
Temperature dependant current limit threshold reduction
