Description
This dual H-bridge motor driver is extremely small and compact, but it can deliver very high power of up to 7A per output current. It uses similar logic as the L298 motor driver, where you control the driver with 3 pins (IN1, IN2, ENABLE).
This motor driver is driven by high power MOS transistors, with the control signals isolated via optocouplers to protect any delicate circuitry. There are also built in power supression to counter any voltage spike. You can drive this motor driver with both 3.3V and 5V logic.
