This is a 4 channel stepper motor driver module based on ULN2003 IC. This motor driver PCB provides a direct driver interface between your microcontroller and motor. The module provides 4 inputs for connection to your microcontroller, power supply connection for stepper motor voltage, and ON/OFF jumper, a direct connect stepper motor header, and 4 LEDs to indicate stepping state.
- Onboard 4 LED indicator to indicator stepping state
- 5V to 12V power supply
- Reliable and low cost
