The H-bridge Unit is a DC motor drive module, using the STM32F030 and RZ7899 scheme to enable the motor drive function, and uses I2C communication with the M5 host to enable PWM control speed, forward, backwards and braking functions. The module has reliable over-current, over-voltage, and over-temperature protection functions, which can ensure the safe operation of the motor. It also has 6-12V and 5V switching circuits in the circuit to adapt to the input power requirements of different motors, which are widely used in 'robots, motor drives, industrial automation, smart homes' and other fields.
