Stepper Driver Module consists of ULN2003-IC which is used to drive the stepper motor.
Use ULN2003 driver chip, 500mA
A. B. C. D LED indicating the four phase stepper motor
White jack is the four phase stepper motor standard jack.
Power pins are seperated
- IN1-4 to the MCU pins
- The pins in the white jack (from left to the right) are: VCC, A, B, C, D (to the stepper motor)
- Power pins are on the right, use jumper to choose either 5V or 12V
