M5Stack Stepmotor Driver Module v1.1 (HR8825)

Description M5Stack Stepmotor Driver Module v1.1 (HR8825) Incorporates STM32+HR8825 stepper motor drive scheme Provides four sets of input signal terminals Features integrated PWR485 communication interface Supports UIFlow graphical programming for precise control Ideal for stepper motor motion control applications The M5Stack Stepmotor Driver Module v1.1 (HR8825) is a sophisticated stepper motor driver that is compatible with the M5 main control. It employs an STM32+HR8825 stepper motor drive scheme, offering a three-way bipolar stepper motor control interface. When the driver is stacked with the M5 main controller, the ESP32 internal signal of the main control directly links to the driver chip, enabling independent control or multi-axis motor linkage. The module incorporates an STM32F030F4P6 chip for IO expansion and provides four sets of input signal terminals and one set of driver chip enable control. Through I2C communication, it can control and monitor the reset
