This Bipolar stepper motor driver module is a combination of two ICs. L297 and L298. L297 stepper motor controller IC generatesfour phase drive signals for two phase bipolar stepper motors. L298 receives the signal and lets you rotate a bipolar stepper motor.
Input pins are given on the left side of the board. Using these pins you must connect the board to a micrcontroller or Arduino and send control signals.
This board can operate one Bipolar stepper motor at a time. Connect the wires of the stepper motor to the connectors marked with A B C D.
