Subject Distance 0.56 Caption An Arduino Nano control board (blue) provides USB control of a stepper motor driver board (green) that then drives a 5V stepper motor. A power inlet allows running the motor off of a 12V supply for higher impulse current allowing the motor to run considerably faster with higher torque.
