Stepper Motor 5V With ULN2003 H Bridge Driver

AED 19.95



This robotic kit includes a stepper motor and driver that are ready to use. the 28BYJ-48 motor is a  5V high torque stepper motor with even more than 2000 steps per revolution. Its torque is sufficient to operate miniature robots. With the ULN2003 driver module, you can simply operate the 28BYJ-48 stepper motor from an MCU like the Arduino Uno. The motor can be linked with a gear shaft and propeller. The stepper motor cable has a 5-wire socket on one side of the board, which also has four LEDs to show which coil is powered at any one time. It always helps that the motor cable only has one direction of travel. You have a motor on/off jumper on the side you should keep it on to enable power to the stepper.

Pinout Of the Module:


IN1 – IN4 pins are used to drive the motor. Connect them to the digital output pins on the Arduino.

GND is a common ground pin.

VDD pin supplies power to the motor. Connect it to an external 5V power supply. Because the motor draws a lot of power, you should NEVER use the 5V power from your Arduino to drive this stepper motor.

Motor Connector This is where the motor plugs in. The connector is keyed, so it only goes one way.
