Description
The ULN2003A unipolar stepper motor driver is an array of seven NPN Darlington transistors capable of 500 mA, 50 V. It contains common-cathode flyback diodes for switching inductive loads. The inputs are compatible with TTL and 5-V CMOS logic.
The ULN2003A is built into the module for easy stepper motor connection. It is suitable for 4 phase stepper motor.
The jumper is intended to turn off the power supply of the stepper motor.
