Description
The ULN2003 stepper motor driver PCB provides a direct drive interface between your microcontroller and stepper motor. The PCB provides 4 inputs for connection to your microcontroller, power supply connection for the stepper motor voltage, and ON/OFF jumper, a direct connect stepper motor header and 4 LEDs to indicate stepping state.
Stepper Motor Connection:
Connect stepper motor to this header. If you use one of our stepper motors they will just plug directly into the header. If you have another brand without the correct header plug, you could solder the wires directly to the back of the PCB.
Step State LEDs:
Indicate which channel is active.
