L293D motor shield for Arduino UNO and MEGA - 2 DC motors, up to 36 V

Product Overview

• Motor control module for Arduino UNO and MEGA boards
• Controls two DC motors or one stepper motor independently
• 5 V logic, separate motor supply up to 36 V
• Four digital outputs on the board for motor control
• Current consumption up to 600 mA per motor
• Directly plugs into the Arduino board without additional wiring

Product Description

This motor control expansion module is based on the L293D driver and plugs onto Arduino UNO and MEGA boards. It enables the microcontroller to drive two DC motors independently or control one stepper motor without the need for external driver components.

The L293D chip can rotate each motor either forwards or backwards and regulate its speed using PWM signals. The module's logic side operates at 5 V and uses four digital outputs of the Arduino; the motor power comes from a separate power source of up to 36 V, so the Arduino itself is not subjected to the motor load. This also allows motors with higher current consumption of up to 600 mA per motor to be controlled safely.

Applications include vehicle-like robots with two driven wheels, robotic grippers with stepper motors, and the construction of experimental setups for educational purposes. A typical project is a mobile robot controlled by radio or infrared signals that only needs to coordinate the speed and direction of both motors.

Operation requires a separate 5 V power supply for the logic and a dedicated power source for the motors, usually a battery pack or an external power supply in the range of 6 V to 36 V. The four required Arduino outputs (two per motor for direction and PWM for speed) must still be available; conflicts may arise with Arduino shields that use a different pin assignment.

Safety Notice

This module is not intended for installation in household electrical circuits and is exclusively designed for building prototypes and for testing and development purposes. Motor supply voltages above 12 V require special attention; if you are unsure about correct polarity or voltage sizing, consult a qualified electrician.
