![[EOL] Stepmotor Driver Module (HR8825)](http://shop.m5stack.com/cdn/shop/files/M039_1200x1200.webp?v=1682559329)
This product is EOL. Please order the new version Module13.2 Stepmotor Driver v1.1
Description
Module13.2 Stepmotor Driver is a stepper motor driver compatible with M5 controllers, utilizing the HR8825 stepper motor driver chip, providing 3 dual-channel stepper motor control interfaces. When stacked with an M5 controller, the internal ESP32 generates signals directly connected to the driver chip, enabling independent control or multi-axis motor coordination. The module integrates a TCA9554 IO expansion chip, offering 4 sets of input signal terminals + 3 sets of stepper motor microstep control + 1 set of driver chip enable control, controlled via the I2C interface. It can monitor and control the status of these 8 expanded IOs, suitable for external limit switches, dynamic microstep adjustment, and motor braking functions. The module also integrates a PWR485 communication interface (RS485 + 9-24V power input) and a DC-JACK, allowing for flexible power supply while enabling communication. It supports UIFlow graphical programming and ESP32-GRBL firmware, web control, making it easy to configure signal output for more precise control of stepper motors. This module is suitable for various stepper motor motion control scenarios, such as printers, robotic arms, etc.
