Unit BLDC Driver

SKU:U181

Description

Unit BLDC Driver is a driver unit specially designed for brushless DC (BLDC) motors. It adopts an STM32 MCU as the main controller and communicates via I2C to precisely control the DRV11873PWPR motor-driver chip, enabling PWM speed regulation, direction switching, and more. The driver chip features a simplified control interface and integrated stall protection, providing efficient and low-noise operation for small three-phase BLDC motors. The on-board STM32 upgrade interface facilitates firmware updates and functional expansion, making it ideal for industrial automation, smart robotics, precision instruments, and other fields.
