Unit HBridge

SKU:U160

Description

Hbridge Unit is a DC motor drive module, using "STM32F030+RZ7899" scheme to realize the motor drive function, and using I2C communication with the M5 host to realize PWM control speed, forward, backward and braking functions. The module has reliable over-current, over-voltage, over-temperature protection function, which can ensure the safe operation of the motor, and 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.

470uF Aluminum Electrolytic Capacitor

The accompanying aluminum electrolytic capacitor should be connected to the positive and negative terminals of the power input. It serves to provide buffering and protection for the circuit. Be careful not to reverse the connections!

Motor Power Selection

The Unit HBridge integrates an internal DC/DC buck converter, which can step down the external 6 ~ 12V input at the 3.96 terminal to 5V to accommodate the power requirements of different motors. A power switching switch is also provided, which allows you to select whether the motor power uses the external 6 ~ 12V input or the 5V output from the DC/DC buck converter. In practical use, please choose the appropriate drive voltage according to the motor specifications.
