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.

ON/OFF Jumper-
 Isolates power to the stepper Motor

Power to drive stepper motor. Make sure it matches the rating of the stepper motor you are using

Microcontroller Connection
Connect 4 outputs from your microcontroller to the four inputs

Supply Volts: 5-12VDC
Maximum Current per output: 500mA
 The driver board accepts a four bit command from any microcontroller and in turn applies the necessary power pulse to step the motor. At the heart of the driver is a ULN2003AN integrated circuit. The board can supply between 5V to 12V to the motor from an independent power supply. It also has a bank of LED’s that correspond to the input signals received from the controller. They provide a nice visual when stepping. 

Some typical stepper motor details: 
• Model: 28KYJ-48 
• Voltage: 5VDC 
• Phase: 4 
• Step Angle: 5.625° (1/64) 
• Reduction ratio: 1/64
