L293 MODULE

The L293D Motor Driver Module uses the L293D dual H-bridge IC to control up to 2 DC motors with independent direction and PWM speed control. Motor supply 4.5–12V; logic supply 4.5–5.5V. Screw terminals for motor connections and standard pin headers for MCU interface. Suitable for robotics, line followers, and mechatronics projects.

Note: Tie all grounds together — Arduino, power source, and motor controller.

Pin Configuration:

• EnA — PWM enable for Motor A
• In1 / In2 — Direction control for Motor A
• Out1 / Out2 — Motor A output
• In3 / In4 — Direction control for Motor B
• Out3 / Out4 — Motor B output
• EnB — PWM enable for Motor B
• 12V — Motor supply (5–35V)
• 5V — Logic supply (or 5V out if motor supply >7V)
• GND — Ground
