Description

Unit HBridge is a DC motor driver module that uses the "STM32F030 + RZ7899" solution to achieve motor driving functions. It communicates with the M5 host via I2C to implement PWM control of speed, forward, reverse, and braking functions. The module has reliable overcurrent, overvoltage, and overheating protection functions to ensure the safe operation of the motor. Additionally, it includes a circuit that switches between 6 ~ 12V and 5V to accommodate different motor input power requirements. This product is widely used in robotics, motor driving, industrial automation, and smart home applications.

Motor Power Selection

Motor Power Selection
The Unit HBridge integrates an internal DC/DC buck circuit that can reduce the 6 ~ 12V input from the external 3.96 terminal to 5V to adapt to different motor power requirements. It also provides a power switch to choose whether the motor power uses the external 6 ~ 12V input or the 5V after DC/DC buck. In actual use, please select the appropriate drive voltage according to the motor specifications.
