TB6612FNG Dual Motor Driver Carrier independent control of bipolar stepper motor / two bidirectional DC motors

This small board is an easy way to use Toshiba's TB6612FNG dual motor driver, which can independently control two bidirectional DC motors or one bipolar stepper motor. A recommended motor voltage of 4.5V to 13.5V and peak current output of 3A per channel (1A continuous) make this a great motor drive for low power motors. The TB6612FNG(308k pdf) is a great dual motor driver that is perfect for connecting two small DC motors like our micro-metal gearmotors to a microcontroller and it can also be used to control a single bipolar stepper motor. The MOSFET-based H-bridges are much more efficient than the BJT-based H-bridges used by older drivers such as the L298N and Sanyo LB1836M, which allows more power to be supplied to the motors and less to be taken from the logic supply (the LB1836 still has the TB6612 for truly low voltage applications). Our small breakout board gives you direct access to all functions of the TB6612FNG, adding power supply capacitors and resetting the battery protection on the motor supply (note: there is no reverse protection on the Vcc connector). ichNa typical application, power connections are made on one side of the board and control connections are made on the other side. All control inputs are pulled internally. Each of the two motor channels has two directional control pins and a speed control pin that has a PWM input with a free-to 100 kHz. The STBY pin must be raised to bring the driver out of standby mode. The distance between the headers on the board is 0.1" smaller than a standard 0.6" DIP packet, but the pin spacing allows it to fit comfortably into 0.1" breadboards and perfboards. The TB6612 motor driver used on the motherboard has a peak current of 3A per channel. The peak values are for fast transients (e.g. when a motor is switched on first), and the continuous rating of 1A depends on various conditions such as ambient temperature. The current current you can supply depends on how well you can keep the motorist cool. The carrier's circuit board is designed to extract heat from the motor driver chip, but performance can be improved by adding a heat sink. This product can be hotEnough to burn you long before the chip overheats. Be careful when handling this product and other related components. A 1 × 16-pole breakout 0.1" male headband is included in the TB6612FNG motor driver. This strip can optionally be soldered to the carrier board so that it can be used with perfboards, solderless bread cabinets or 0.1" connectors. (The headers could be used as two 1 × 8 pieces or as a single 1 × 16 piece that can be broken in half.)
