The wiring method for stepping motor:
Left 1 N 1 ? 1 N 4 connect to the four corresponding IO wires of MCU.
The right black pins are defined from top to VCC, A, B, C, D (connect to the concentric line, phase A, B, C, D of stepping motor).
Power supply method:
Connect short circuit jumper, choose 5V as the working voltage for stepping motor/DC motor. Take off short circuit jumper, stepping motor/DC motor can choose external voltage for power supply via pins.
ULN2003 Driver Board
