Note that the output channels of both the L293D ICs are broken out to the edge of the motor shield with two 5-pin screw terminals (M1-M2-M3-M4)to connect four dc motors having voltages between 4.5V to 25V DC. This is the official (Adafruit) schematic drawing of the motor shield. The next key component of the motor shield is the 74HC595 shift register IC that extends 4 digital pins of the Arduino to the 8 direction control pins of the L293D ICs.

The shield offers a total of four H-Bridges and each H-bridge can deliver up to 600mA drive current to the dc motor.

The motor driver shield comes with two L293D dual-channel H-Bridge motor ICs, so it can individually drive up to four dc motors. Besides such devoted dc motor shields will help you to drive certain solenoids and electromechanical actuators. Quite often you’ll need a full-featured motor shield for your Arduino based mechatronics projects as such a compact shield can control a number of everyday dc motors, servo motors, and stepper motors. I’ve just presented briefly how it’s enough to inspire me! L293 motor driver shield This is not intended to be an in-depth tutorial as there is plenty of information already out there.

Well, I figured it’s about time that I shared my own experiences with the L293 Arduino Motor Driver Shield.

The L293 Arduino Motor Driver Shield, in particular, is extremely elegant, and I wanted to see how to play with that gem.

  • Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.On COVID-19 lockdown days, I came across several motor driver modules in my scrap box in the attic – surprisingly most of them are unused Chinese modules.
  • Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution).
  • 4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection, internal kickback protection diodes.
  • 2 connections for 5V ‘hobby’ servos connected to the Arduino’s high-resolution dedicated timer.
  • The output enables the L293D is directly connected to PWM outputs of the Arduino. The shift register expands 3 pins of the Arduino to 8 pins to control the direction of the motor drivers.

    The shield contains two L293D motor drivers and one 74HC595 shift register. The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. Basically, this means using this chip you can use DC motors and power supplies of up to 36 Volts, that some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what’s known as a type of H-Bridge. L293D is a monolithic integrated, high voltage, high current, 4-channel driver. It drives the DC motor and stepper with the L293D, and it drives the servo with Arduino pin9 and pin10. This Arduino compatible motor Driver shield is a full-featured product that it can be used to drive 4 DC motor or two 4-wire steppers and two 5v servos. That makes it a great shield for any robotic project. This L293D Motor Driver/Servo Shield for Arduino is probably one of the most versatile on the market and features 2 servo and 4 motor connectors for DC or stepper motors.
