The L293D Motor Driver Shield for Arduino runs four bi-directional DC motors or two stepper motors. Using integrated H-Bridges, it handles high-current loads across a 4.5-36V range. An onboard 74HC595 shift register reduces the digital pin count needed on Uno or Mega controllers.
Key Features
- 4-Channel DC Control: Drives 4 bi-directional DC motors with 8-bit speed selection. Independent movement works for complex 4-wheel robot chassis.
- 74HC595 Shift Register: Serial-to-parallel conversion manages motor signals through minimal Arduino pins. This keeps digital pins open for ultrasonic sensors or displays.
- Thermal Protection: Built-in shutdown circuitry and kickback protection diodes handle voltage spikes. Chip burnout won't occur during sudden motor stalls.
- 600mA Output Current: Provides 600mA continuous current per channel with 1.2A peak capacity. Standard yellow geared motors run without overheating the driver chips.
- Dual Servo Ports: Two dedicated headers connect to the Arduino's high-resolution hardware timers. Jitter-free control works for robotic arm or gripper movements.
- External Power Input: Dedicated terminal blocks separate motor power from the Arduino logic circuit. High-voltage motors won't fry the microcontroller during heavy load shedding or spikes.
Frequently Asked Questions
Can L293D shield drive 4 DC motors?
This shield controls four independent DC motors with full speed and direction control. Two L293D driver chips manage the 4-channel output simultaneously.
Does L293D motor shield need external power?
External power is necessary for motors exceeding the Arduino's 500mA USB current limit. Connecting a battery to the EXT_PWR terminals prevents logic circuit brownouts.
