Info
product url - L293D Arduino Motor Shield
This shield has an L293D IC, a dual H-bridge motor driver integrated circuit (IC), which allows it to drive
- two DC motors,
- a stepper motor,
- or a servo motor.
Key Features of the L293D Motor Driver Shield
- Dual H-Bridge IC: The L293D IC can control up to two DC motors or one stepper motor. It provides bidirectional control for two motors independently.
- Current Handling: Each channel of the L293D can handle up to 600mA of continuous current and peak currents up to 1.2A per channel.
- Voltage Range: The shield can operate at a wide range of voltages, typically from 4.5V to 36V.
- Protection Diodes: The shield has built-in diodes to protect the IC from back EMF generated by the motors.
- PWM Control: Supports Pulse Width Modulation (PWM) for speed control of the motors.
