Powerful motor drive board, steering gear, stepper motor, DC small motor
I2C interface, the motor is not enough, a superimposed, double the number of drive motor.
1- fully compatible with the expansion of the arduino interface
2- Via I2C and arduino communication, the address can be modified
3-can be connected to two servo, direct output PWM drive
4-can take 4 DC brush motor or 2 4-wire stepper motor
6-using the TB6612FNG motor driver chip, 1.2A drive capability, peak 3.2A, spike L298N module
We have upgraded the shield kit to make the best, 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 a L293D darlington driver, we now have the TB6612 MOSFET driver: with 1.2A per channel and 3A peak current capability. 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 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 also makes it drop-in compatible with any Arduino, such as the Uno, Due, Leonardo and Mega R3.
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 on 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 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.
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 & Due milanove. 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 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.
