The L293D motor driver module is a popular and widely used board for controlling DC motors and stepper motors in embedded and robotics projects. It is based on the L293D IC, which is a dual H-bridge motor driver. The module allows you to control the direction and speed of two DC motors simultaneously, or one stepper motor.
🧠 Key Features of L293D IC
