This board/chip uses I2C 7-bit addresses between 0圆0-0x80, selectable with jumpers.Īs of we are shipping motor shields with the terminal blocks, and power jumper pre-soldered on./* * Created by ArduinoGetStarted. We have a great tutorial in the Adafruit Learning System with a lot of documentation and example code, so please check it outĭimensions, assembled: 70mm x 55mm x 10mm 2.7″x2.1″x0.4″ Stacking headers not included, but we 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 we have lots of motors in the shop and all our hobby servos, DC motors, and stepper motors work great. Some soldering is required to assemble the headers on. Place the shield on top of the header pins, they should fit into each of the holes along the edge. Break apart the 0.1' header into 6, 8 and/or 10-pin long pieces and slip the long ends into the headers of your Arduino. Works with Mega/ADK R2 and earlier with 2 wire jumpers.ĭownload the easy-to-use Arduino software library, check out the examples and you're ready to go!Ĭomes with an assembled & tested shield, terminal block, plain header, jumper. Check you have everything you need: assembled shield PCB, 0.1' male header, 4 of 3x4 male header, and a 2 pin terminal block. Tested compatible with Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila & Duemilanove. Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies

Motors automatically disabled on power-upīig terminal block connectors to easily hook up wires (18-26AWG) and power Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution) Note that the distance between digital pins 7 and 8 is 160 mil (0.16'), not an even multiple of the 100 mil spacing of the other pins. Three screw holes allow the shield to be attached to a surface or case. 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.Ģ connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer – no jitter!Ĥ H-Bridges: TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Controlling servomotors with an Arduino and a Sensor Shield V5.0 is a relatively straightforward process. The maximum length and width of the Proto Shield PCB are 2.7 and 2.1 inches respectively. Lots of other little improvements such as a polarity protection FET on the power pins and a bit of prototyping area. This also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.Ĭompletely 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. Only two pins (SDA & SCL) 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 chip handles all the motor and speed controls over I2C. Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. 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 a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. 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: We have upgraded the shield kit to make the bestest, easiest way to drive DC and Stepper motors. The original Adafruit Motorshield kit is one of our most beloved kits, which is why we decided to make something even better.
