H-bridge Unit v1.1 (STM32F030)

This HBridge v1.1 Unit is a DC motor drive module that is powered by the STM32F030 microcontroller and RZ7899 driver chip. It provides I2C communication with the M5 host, and accurate PWM control for speed adjustment and easy management of forward, reverse, and braking functions.

Safety and reliability come first with built-in protections against over-current, over-voltage, and over-temperature. The module features a total power MOSTUBE switch circuit for dynamic motor control and an integrated current acquisition circuit for safe motor operation. It adapts to various needs with a smart 6-12V and 5V switching circuit, making it ideal for robotics, motor drives, industrial automation, and smart homes.

Note: Aluminum electrolytic capacitors connected to the positive and negative poles of the power input can provide buffer protection for the circuit. Be careful not to connect them in the opposite direction
