The L293D Motor Shield for Arduino is a versatile and efficient motor driver board designed for robotics, automation, and DIY electronics projects in Bangladesh. This shield is equipped with two L293D dual H-bridge motor driver ICs and one 74HC595 shift register, enabling it to control up to 4 DC motors, 2 stepper motors, or 2 servo motors simultaneously. It is widely used in robotics, 3D printers, CNC machines, smart cars, and various automation projects where precise motor control is required.

This shield allows bidirectional control of DC motors and supports PWM speed control, making it ideal for applications requiring precise speed and direction adjustment. With motor voltage support from 4.5V to 25V and a continuous current output of 1.2A per channel, it is suitable for both low-power and moderate-power robotics projects. The shield plugs directly onto Arduino Uno and other compatible boards, simplifying the wiring process and improving efficiency.
