Pinout
10| Pin | Name | Functions | Notes |
|---|---|---|---|
| VDD | VDD | POWER | Logic voltage input |
| + | Motor Voltage Input | POWER | Supply 5V to 29VDC for your motor |
| GND / - | GND | GND | Common ground for power and logic |
| DIR | Direction Control Pin | GPIO | Set high or low to set spin orientation. High turns motor clockwise, Low counterclockwise |
| STEP | Microstep Control Pin | GPIO | Toggle for one step/microstep at a time. Default 1/8 microstep mode |
| MS1 | Microstep Selection Pin 1 | GPIO | Pull high to change default 1/8 microstep mode |
| MS2 | Microstep Selection Pin 2 | GPIO | Pull high with MS1 for different modes (e.g., 1/16) |
| DIAG | Diagnostic Pin | GPIO | Driven high if motor driver issues |
| INDEX | Index Output Pin | GPIO | High when microstep counter is at zero position |
| UART | UART Interface Control Pin | UART | Single-pin serial port with auto-baud detection for precise communication, diagnostics and control. Requires a microcontroller library. |
