Unit HBridge v1.1

SKU:U160-V11

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.

Motor Power Selection

Motor Power Selection
The Unit HBridge v1.1 integrates a DC/DC step-down 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 select whether the motor power uses the external input of 6 ~ 12V or the 5V after DC/DC step-down. Please choose the appropriate driving voltage according to the motor specifications during actual use.
