Key Features

🔌 Dual H-Bridge Motor Driver (L293D)

At the heart of this expansion board is the L293D motor driver IC, a robust dual-channel H-bridge capable of driving two DC motors independently or one stepper motor. It supports both bidirectional control and speed regulation via PWM signals, giving you precise movement control for your projects.

Each channel can handle up to 600mA continuous current (1.2A peak) at voltages from 4.5V to 25V, making it ideal for small to medium DC motors.

⚙️ Full Arduino Compatibility

This module is fully compatible with Arduino UNO, Mega, Nano, and other similar boards. It connects directly to the Arduino headers, simplifying wiring and setup. The shield’s plug-and-play design makes it beginner-friendly and time-saving for prototyping.

🧠 Easy Motor Control via Code

Using the Arduino IDE and basic motor control libraries, users can easily program speed, direction, and braking functions. You can even combine it with sensor modules or wireless controllers to build autonomous or remote-controlled robots.

🔋 Separate Power Supply Support

The Mini L293D Motor Shield features independent power input for the motor supply (Vs) and the logic circuit (Vss). This allows you to use external power sources for motors while keeping your control board safely powered at 5V. The built-in voltage regulator and protection circuitry ensure safe operation.

⚡ Overcurrent and Thermal Protection

The L293D IC includes built-in diodes for back EMF protection and thermal shutdown to prevent damage from overheating or excessive current. This extends the lifespan of both your motors and your driver board.

🪶 Compact and Durable Design

With its miniature form factor and high-quality PCB construction, the board is designed to fit into small enclosures or compact robots. The durable components ensure long-term performance even in continuous operation environments.
