Unit 4EncoderMotor Driver

SKU:U233

Description

Unit 4EncoderMotor Driver is a 4-channel encoder DC motor driver unit featuring an STM32F030C8T6 main controller. It uses an I2C communication interface and provides four DC 5V motor outputs with corresponding A/B encoder inputs, making it suitable for 6-wire encoder geared motors and TT geared motors. The driver supports PWM speed control, forward/reverse control, and closed-loop speed and position control. It integrates an INA199A current-sensing circuit and motor operating voltage detection, enabling real-time monitoring of motor current and voltage.

Two onboard HY2.0-4P Grove ports share the same I2C bus, making it easy to connect additional I2C devices. The I2C address is software-configurable, allowing multiple driver units to be connected to the same bus and expand the number of motor drive channels. The unit accepts an external DC 6 ~ 12V input and, through its onboard DC-DC buck converter, provides a total output capacity of up to DC 5V@8A. This output can power motors and also supply power to a host device through the Grove interface. An onboard programmable RGB LED indicates the device operating status. The unit is suitable for multi-joint robots, wheeled chassis, robotic arms, and similar applications.
