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 \u003cstrong\u003e4 sets of input signal terminals\u003c\/strong\u003e + \u003cstrong\u003e3 sets of stepper motor microstep control\u003c\/strong\u003e + \u003cstrong\u003e1 set of driver chip enable control\u003c\/strong\u003e, 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 \u003cstrong\u003ePWR485\u003c\/strong\u003e communication interface (\u003cstrong\u003eRS485\u003c\/strong\u003e + \u003cstrong\u003e9-24V power input\u003c\/strong\u003e) 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.\u003c\/p\u003e\n\u003cdiv style=\"\n  background: #fff8e1;\n  border: 1px solid #ffe0a3;\n  border-left: 4px solid #f9a825;\n  border-radius: 8px;\n  padding: 14px 16px;\n  margin: 24px 0;\n\"\u003e\n  \u003cstrong style=\"\n    display: block;\n    color: #8d6e00;\n    font-size: 15px;\n    margin-bottom: 6px;\n  \"\u003e\n    Precautions\n  \u003c\/strong\u003e\n\n  \u003cspan style=\"\n    color: #2c2c2c;\n    font-size: 14.5px;\n    line-height: 1.6;\n  \"\u003e\n    Do not plug or unplug the motor while powered on.
