[EOL] Stepmotor Driver Module (HR8825)

PRODUCT DETAILSDescription StepMotor Driver is adapted to M5 core series, the HR8825 chip solution provides a 3-way bipolar stepper motor control interface. You can implement independent control or multi-axis motor linkage after this module is stacked with M5 core series of the internal ESP32 generates signals directly to the driver chip.This module integrated TCA9554 IO expansion chip provides 4 sets of input signal terminals + 3 sets of stepper motor subdivision control + 1 set of drive chip enable control, through the I2C interface control, can monitor and control the 8 expansion IO state, as well as for external limit switch, dynamic subdivision adjustment, motor braking. Integrated PWR485 communication interface (RS485 + 9-24V power input) and DC-JACK, which can be used for communication and more flexible power supply. Download the UIFLOW and you're ready to go!With ESP32-GRBL firmware, web control. It can be easy to configure signal output and very useful when you need to positio
