Description
M5Stack Unit BLDC Driver is a compact BLDC motor driver unit designed for small three-phase sensorless motors. Built around an STM32 motor controller and the DRV11873PWPR driver chip, it communicates over I2C at address 0x65 and supports PWM speed configuration, direction switching, and reliable protection handling. That makes this unit a practical fit for brushless motor control, compact robotics, and industrial automation motion tasks that need low-noise operation.
