Product Description

L293D Motor Driver Shield for Arduino

Versatile Motor Control Shield for Robotics and Automation Projects

The L293D Motor Driver Shield is a popular expansion board designed to simplify motor control with Arduino. It acts as an intermediary between the microcontroller and motors, enabling safe and controlled operation of DC motors, stepper motors, and servos [citation:1][citation:6].

AllinOne Motor Control - Drives up to 4 DC motors, 2 stepper motors, and 2 servos simultaneously
Builtin Protection Thermal shutdown, internal kickback protection diodes, and pull-down resistors
Motor supply voltage range: 4.5V to 24V [citation:1]
Output current: 600mA continuous, 1.2A peak per channel [citation:4][citation:11]
Use external power supply for motors to ensure stable operation
Power jumper must be configured correctly - incorrect setup can damage the shield and Arduino [citation:6]

Key Specifications and Features

ParameterValue
Motor Channels4 DC motors / 2 stepper motors
Servo Headers2 dedicated (D9, D10 PWM)
Voltage Range4.5V to 24V DC [citation:4]
Current Capacity600mA continuous, 1.2A peak [citation:9]
Logic Voltage4.5V to 5.5V [citation:2]
CompatibilityArduino UNO, Mega, Leonardo [citation:1][citation:4][citation:11]

The shield features two L293D ICs, each providing dual H-bridge drivers [citation:1]. A 74HC595 shift register reduces the number of Arduino pins required for motor control [citation:1][citation:11].

Hardware Overview and Pin Usage

*Motor Ports:*

  • M1, M2, M3, M4 → DC motors [citation:1]
  • M1 + M2 → Stepper motor 1
  • M3 + M4 → Stepper motor 2

*Servo Ports:*

  • SERVO_1 → PWM pin D10 [citation:1]
  • SERVO_2 → PWM pin D9 [citation:1]

The shield internally uses pins D3, D4, D5, D6, D7, D8, D9, D10, D11, D12 [citation:1]. Analog pins A0-A5 can be repurposed as digital inputs for additional functionality.

Troubleshooting

Motor not responding:

  • Verify external power supply is connected and within 4.5V-24V range
  • Check power jumper configuration
  • Ensure pulldown resistors keep motors disabled during powerup

Servo jittering:

  • Servos connect to high-resolution dedicated timer pins (D9, D10) for stable control [citation:4]
  • Avoid using high-power servos without external power supply [citation:6]

Shield not working:

  • Ensure proper alignment with Arduino headers
  • Check that the shield does not cover the reset button and other components [citation:4]
