The shield supports PWM speed control and polarity control. The driver shield includes two TB6612FNG motor driver chips, compared with the traditional L298N chip, efficiency is improved and the component size also greatly reduced. The chip doesn't heat in to the rated range, and a single path maximum output 1.2A continuous current. The module includes a built-in low voltage detection circuit and thermal shutdown protection circuit, which is safe and reliable. This module is suitable for all kinds of DIY production. Specification        VM Motor Power Supply: 2.5 V ~ 13.5 V  VCC Logic Power Supply: 2.7 ~ 5.5 V  Output Current: 1.2A continuous current (per channel)  Start/Peak Current: 2A (continuous pulse) / 3.2A (single pulse)  Arduino Control Port: Digital pins 3, 4, 5, 6, 7, 8, 11, 12   Working Temperature: ‐20 ~ 85    Dimensions: 53mm x 52mm/2.09 x 2.05  Board Overview Motor I/O    Motor  Direction  Forward  Backward  Speed  Speed range   M1   4   LOW   HIGH   3   0‐255   M2   12  HIGH   LOW   11   0‐255   M3   8  LOW   HIGH   5  0‐255   M4   7  HIGH   LOW   6  0‐255   Tutorial You Will Need   Hardware   o DFRduino UNO R3 x 1  o Quad Motor Shield for Arduino x 1  o DC motor x 4  o Jumper Wires  Software   o Arduino IDE Click to download Arduino IDE   https://www.arduino.cc/en/Main/Software  Connection Diagram Sample Code Sample Code 1 /*! 2 * @file QuadMotorDriverShield.ino 3 * @brief QuadMotorDriverShield.ino Motor control program 4 * 5 * Every 2 seconds to control motor positive inversion 6 * 7 * @author linfeng(490289303@qq.com) 8 * @version 9 * @date V1.0 2016-4-5 10 */ 11 const int E1 = 3; ///
