Description

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 position something very accurately. such as:printers, robotic arms, etc.

Note:
It is forbidden to plug or unplug the motor when it is powered on. All operations should be performed after the device is powered off to avoid damage to the module.
