Unit BLDC Driver

SKU:U181

Description

The Unit BLDC Driver is a driver unit specifically designed for Brushless DC (BLDC) motors. It uses the STM32 as the main control chip and achieves precise control of the DRV11873PWPR motor driver chip through I2C communication, enabling PWM speed control, monitoring, direction switching, and other functions. The driver chip features a simplified control interface and integrated stall protection, ensuring efficient and low-noise operation of three-phase small BLDC motors. The onboard STM32 upgrade interface facilitates firmware updates and functional expansions, making it suitable for industrial automation, smart robotics, precision instruments, and other fields.
