BDD L293D DC Motor Driver Shield 4 Motor 2 Stepper for Arduino

The BDD L293D DC Motor Driver Shield is a versatile motor control expansion board designed for Arduino Uno, Mega, Diecimila, and Duemilanove development boards. Featuring four L293D H-Bridge motor driver ICs, the shield can independently control up to four DC motors, two stepper motors, or two RC servo motors, making it ideal for robotics, automation, and STEM projects.

Each H-Bridge delivers 0.6A continuous current (1.2A peak) with built-in thermal protection, allowing reliable control of motors operating from 4.5V to 16V DC as standard. With suitable capacitor upgrades (C6 and C7), the motor supply can support voltages up to 36V DC.

The shield provides 8-bit PWM speed control (256 speed levels) for each DC motor, enabling smooth acceleration and precise speed adjustment. Dedicated servo connectors utilise Arduino's hardware timer for stable, jitter-free servo operation, while separate logic and motor power inputs improve system stability and performance.
