Adafruit Motor/Step/Servo Shield - v2.3 for Arduino v2 Kit

Adafruit Motor/Step/Servo Shield - v2.3 for Arduino v2 Kit

The original Adafruit Motorshield kit has been one of our most beloved kits, so we decided to make something even better. We upgraded the shield kit to make the best and easiest way to drive DC and Stepper motors. This shield will make quick work of your next robotics project! We kept the ability to drive up to 4 DC motors or 2 stepper motors, but added many improvements:

Instead of an L293D darlington driver, we now have the TB6612 MOSFET drivers with 1.2A per channel current capability (3A peak) and it has built-in kickback diodes as well. 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, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Only two data pins 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 us 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 big 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.

Features:

• 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 peak) 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.
• Big terminal block connectors to easily hook up wires (18-26AWG) and power
• Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor power
• Comes with Arduino shield stacking headers
• Compact size
• Arduino reset button brought up top
• Plenty of prototyping area, and on the motor driver chips, 2 x 3.5mm pitch screw-terminal blocks for the motor wires. A bit of hand-soldering is required to assemble the shield, but it is not too hard. If you would like to stack shields, we have a set of stacking headers in the shop. A bit of light soldering is required to attach the headers to the shield but it's fast and easy to do.

Note:The terminal block included with your product may be blue or black.
