Description

This kit has 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, this kit has 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.

As well, it is a completely stackable design: 5 address-select pins means up to 32 stackable shield. That adds up to 64 steppers or 128 DC motors. 

  • 2 connections for 5V 'hobby' servos connected to the Arduino's high-resolution dedicated timer
  • 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 
  • Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
  • Terminal block connectors to easily hook up wires (18-26AWG) and power
  • Arduino reset button 
  • Polarity protected 2-pin terminal block and jumper to connect external power
  • Tested compatible with Arduino UNO, Leonardo, ADK/Mega R3, Due, Diecimila & Duemilanove. Works with Mega/ADK R2 and earlier with 2 wire jumpers
  • 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.
