Description
Unit HBridge v1.1 is a DC motor driver module that uses STM32F030 as the main controller and RZ7899 as the driver to achieve motor driving functions. It communicates with the M5 host using I2C and controls functions such as speed, forward, reverse, and braking with (up to 16-bit data) PWM signals. The module features reliable overcurrent, overvoltage, and overheating protection functions. It has a built-in main power MOS switch circuit, supporting programmable dynamic control of motor release/lock. The built-in total current collection circuit can obtain total circuit parameters to ensure the safe operation of the motor. Additionally, the circuit includes a 6-12V and 5V switching circuit to accommodate different motor input power requirements. This product is suitable for fields such as robotics, motor driving, industrial automation, and smart home.
