Storage Temperature-25 Deg C ~ +130 Deg C
Operating Current Range0 ~ 36 mA
Board Thickness1 - 2 mm

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. It drives the DC motor and stepper with the L293D, and it drives the servo with Arduino pin9 and pin10.

L293D is a monolithic integrated, high voltage, high current, 4-channel driver. 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. 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. a motor.


The shield contains two L293D motor drivers and one 74HC595 shift register. The shift register expands 3 pins of the Arduino to 8 pins to control the direction of the motor drivers. The output enables the L293D is directly connected to PWM outputs of the Arduino.

Firmware:
  • Arduino Stepper/Servo software library with microstepping support.
  • To install, click on Download in the top right corner, select zip and uncompress the folder.
  • Rename the folder to AF-motor (check that the renamed folder contains the .cpp and .h files) and install into the Arduino sketches/libraries folder. For information how to use and install libraries, see our tutorial! This version now works with the Mega. Public domain!
  • AccelStepper library with AFMotor support. This library allows for advanced stepper control including acceleration and deceleration, and concurrent stepper control!
  • To install, click on Download in the top right corner, select zip and uncompress the folder.
  • Rename the folder to AF-motor (check that the renamed folder contains the .cpp and .h files) and install into the Arduino sketches/libraries folder.

Note: Power for the motors can be supplied from the Arduino boards DC Jack (normally 9V) or from the 2-pin EXT-PWR terminal block. If you are supplying power from the EXT_PWR terminal block you should remove the PWR jumper or you could damage the shield and the Arduino board.

Product Details:

Input VoltageDC 5-10V
Working voltage2.3~5.5
Size25x61mm
Weight0.35KG
Packaging TypeBox

You can control 16 free-running PWM outputs with 16-Channel 12-Bit PWM/Servo Driver using only 2 pins. You can even chain up 62 breakouts to control up to 992 PWM outputs.

It’s an I2C-controlled PWM driver with a built-in clock. That means you do not need to continuously send it to signal to tie up your microcontroller, it is completely free running!

It is 5V compliant, which means you can control it from a 3.3V microcontroller and still safely drive up to 6V outputs. This is good when you want to control white or blue LEDs with 3.4+ forward voltages. 6 address select pins so you can wire up to 62 of these on a single I2C bus, a total of 992 outputs.

Features :
  • Adjustable frequency PWM up to about 1.6 KHz
  • 12-bit resolution for each output – for servos, that means about 4us resolution at a 60Hz update rate
  • Configurable push-pull or an open-drain output
  • The output enable pin to quickly disable all the outputs
  • Terminal block for power input
  • Reverse polarity protection on the terminal block input
  • Green power-good LED
  • 3 pin connectors in groups of 4 so you can plug in 16 servos at once
  • Chainable design
  • A spot to place a big capacitor on the V+ line
  • 220-ohm series resistors on all the output lines to protect them, and to make driving LEDs trivial.
  • This board/chip uses I2C 7-bit address between 0x60-0x80, selectable with jumpers.

Package Includes :1 x 16-Channel 12-bit PWM/Servo Driver
