Adafruit Motor/Stepper/Servo Shield for Arduino v2.3 Kit
Best and easiest way to drive DC and Stepper motors
Completely stackable design: 5 address-select pins means up to 32 stackable shields: that's 64 steppers or 128 DC motors!
Fully-dedicated PWM driver chip onboard.
Drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.
Assembled and Tested
An upgraded Adafruit Motorshield kit will make quick work of your next robotics project! The ability to drive up to 4 DC motors or 2 stepper motors is still there but many improvements were added. 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. Handles up to 4 bi-directional DC motors with individual 8-bit speed selection and up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. Motors automatically disabled on power-up and power Arduino reset button was brought up top. Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies. Big terminal block connectors to make it easy to hook up wires and power.
Item Specifics Dimensions (assembled): 70mm x 55mm x 10mm (2.7" x 2.1" x 0.4") Includes Shield, Terminal Block, Plain header, Jumper This board/chip uses I2C 7-bit addresses between 0x60-0x80, selectable with jumpers. Shields with the terminal block and jumpers pre-soldered on Some soldering required for headers Stacking headers, Arduino and motors not included Compatible with Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila & Duemilanove and Mega/ADK R2 and earlier with 2 wire jumpers.
