It lets you drive two DC motors with your Arduino/Seeeduino board, controlling the speed and direction of each one independently. You can also measure the motor current absorption of each motor, among other features. The on board DC/DC converter suport a very wide range of input voltage, and can provide a 5V power supply for the microcontroller board with 100mA maximun current.So, you just need one power supply to drive the motors and power up the logic circuit. **Specifications** Operating Voltage: 6V ~ 28V DC/DC output: 5V 100mA @ "5V" pin Output Current(For Each Channel ): 2A (continuous operation) / 5A(peak) Output Duty Range: 0%~100% 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 ![enter image description here][6] **Documents** Please visit our [wiki][7] page for more info about this product.
