The original Adafruit Motorshield kit is one of Adafruit's most beloved kits, which is why Adafruit decided to make something even better. Adafruit have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! Adafruit kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements:

Instead of a L293D darlington driver, Adafruit now have the TB6612 MOSFET drivers with 1.2A per channel current capability (you can draw up to 3A peak for approx 20ms at a time). It also has much lower voltage drops across the motor so you get more torque out of your batteries, and there are built-in flyback diodes as well.

Instead of using a latch and the Arduino's PWM pins, Adafruit have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two data pins (SDA & SCL in addition to the power pins GND & 5V) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or shields to the same pins. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.

Completely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors! What on earth could you do with that many steppers? I have no idea but if you come up with something send Adafruit a photo because that would be a pretty glorious project.

Lots of other little improvements such as a polarity protection FET on the power pins and a bit of prototyping area. And the shield is assembled and tested here at Adafruit so all you have to do is solder on straight or stacking headers and the terminal blocks.

Lets check out these specs again:

  • 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer - no jitter!
  • 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A for brief 20ms peaks) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
  • Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
  • Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
  • Motors automatically disabled on power-up
  • Big terminal block connectors to easily hook up wires (18-26AWG) and power
  • Arduino reset button brought up top
  • Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies
  • Tested compatible with Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila & Duemilanove. Works with Mega/ADK R2 and earlier with 2 wire jumpers.
  • Download the easy-to-use Arduino software library, check out the examples and you're ready to go!

Comes with an assembled & tested shield, terminal block, plain header, jumper. Some soldering is required to assemble the headers on. Stacking headers not included, but Adafruit sell them in the shop so if you want to stack shields, please pick them up at the same time. Arduino and motors are not included but Adafruit have lots of motors in the shop and all Adafruit's hobby servos, DC motors, and stepper motors work great.

Adafruit have a great tutorial in the Adafruit Learning System with a lot of documentation and example code, so please check it out

Technical Details

Details:

  • Dimensions, assembled: 70mm x 55mm x 10mm 2.7"x2.1"x0.4"
  • This board/chip uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers.

Datasheet for the motor driver chip

Revision history:

  • As of 3/21/2014 Adafruit are shipping motor shields with the terminal blocks, and power jumper pre-soldered on. You'll still need to do a little soldering to put on the shield-headers (or stacking headers) but it should be even easier and faster to get started!

    This is really the gold plated version of a motor controller. I bought this to use in prototype testing. It is probably best suited for that situation; it would be a bit of an overkill for 2 motor bots. There are cheaper and just as effective boards available from Adafruit and Df Rpbot , for example.

    This shield is by far the best motor shield I have used and the price is really great. 4DC motor running off one shield makes things so much easier to manage.

    The only downside was that I had to solder the stacking headers on and I really suck at soldering so it took me a while to get them on. However I am now better at soldering so it is not that bad.

    Overall the libraries are easy to use and it is fully compatible with the UNO.

    I would recommend this shield to anyone that needs to drive a couple of motors.

  5. Review by Adam - Great product, except for the polarity protection
    Rating

    Really great product, with good build quality.
    I bought two of these to stack on an arduino uno, and they worked a treat. Fast to put together, easy to run. If you are using it to control steppers I highly recommend the AccelStepper library.
    The only down side is that although they claim to have reverse polarity protection on the power jack I fried one of the onboard micro controllers by accidentally reversing the terminals of my 12V power supply (so it will only run 1 stepper now).
    Aside from that, it is pretty much perfect. (Posted on 25/01/2014)

    These shields work great. I bought two shields to control 8x DC motors (I didn't play with steppers or servos).
    Each shield can be powered from the Arduino power jack or independently from an external power supply. I used an external regulated power supply with my project - I'd recommend this if you are planning on controlling multiple motors as well. Consider what motors you are going to be using and each motors power requirements - each channel has a nominal rating of 1.2A. The shield is intended for use with 6-12VDC motors also.
    Adafruit provides a library to use with this shield, so coding is extremely convenient. There are a few example codes which are quite helpful if you want to get an understanding of the shield capabilities.
    Each shield only comes with male header pins; if you want to make your shield stackable make sure you buy some stackable headers also. (Posted on 19/01/2014)
