      Grove - I2C Motor Driver (TB6612FNG) The Grove - I2C Motor Driver (TB6612FNG) can drive two DC motors up to 12V/1.2A or drive one stepper motor up to 12V/1.2A. With the on-board MCU, it can work with Arduino easily via the Grove I2C interface. This diver board is based on TB6612FNG, which is a driver IC for DC motor and stepper motor with output transistor in LD MOS structure with low ON-resistor. Two input signals, IN1 and IN2, can choose one of four modes such as CW, CCW, short brake, and stop mode. Features    On board MCU  CW/CCW/short brake/stop function modes  Built-in thermal shutdown circuit and low voltage detecting circuit  Standby (Power save) system   Specification Item Value  MCU Operating Voltage  3.3V / 5V  Motor Supply Voltage  2.5 ~ 13.5 (5V Typical, 15V Max.)  Output Current  1.2 A(ave)/3.2 A (peak)  Switching Frequency  100kHz  Logic Interface  I2C  I2C Address  0x14 (default)  I2C Address Range  0x01 ~ 0x7f (Configurable)  Typical applications  DC motor control  Stepper motor control Hardware Overview Pin Out     Hardware Detail I2C Interface This board uses the I2C interface to allow the on-board MCU to communicate with the host computer. GND: connect this module to the system GND VCC: you can use 5V or 3.3V for this module SDA: I2C serial data SCL: I2C serial clock     Power In Provide DC power to the motors, input range 2.5V ~ 13.5V. GND: Connect to the system GND, plug the power "-" VM: Plug the power "+", supply power for the motor. DC Motor Output This board has two channel DC Motor Output, it can output 12V/1.2A per channel. You can use this driver board control two DC motors at the same time. A1: Channel A output 1 A2: Channel A output 2 B1: Channel B output 1 B2: Channel B output 2     Steperp Motor Output You can use this board to control the 4-wire stepper motor as well, it can output up to 12V/1.2A. OUT1: Connected to one input of the stepper motor coil 1. OUT2: Connected to the other input of the stepper motor coil 1. OUT3: Connected to one input of the stepper motor coil 2. OUT4: Connected to the other input of the stepper motor coil 2. Note Actually the DC port and the stepper port are physically connected together. The connection diagram is as follows: DC Port Stepper Port  A1  OUT1  A2  OUT2  B1  OUT3  B2  OUT4      Platforms Supported Arduino Raspberry Pi  BeagleBone  Wio  LinkIt ONE            Caution The platforms mentioned above as supported is/are an indication of the module's hardware or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library. Getting Started Play With Arduino Hardware Materials required DC Motor Demo Seeeduino V4.2 Base Shield  Grove ‐ I2C Motor Driver  (TB6612FNG)  DC Motor          Note 1 Please plug the USB cable gently, otherwise you may damage the port. Please use the USB cable with 4 wires inside, the 2 wires cable can't transfer data. If you are not sure about the wire you have, you can click here to buy 2 Each Grove module comes with a Grove cable when you buy. In case you lose the Grove cable, you can click here to buy. 3 You also need prepare at least 2 jumpers, in case you do not have, you can click here to buy.      Step 1. Plu the DC motor into the DC Motor Output port of the driver board, plug the external DC power into the Power In port.  Step 2. Connect the Grove - I2C Motor Driver (TB6612FNG) to port I2C of GroveBase Shield.  Step 3. Plug Grove - Base Shield into Seeeduino.  Step 4. Connect Seeeduino to PC via a USB cable.

Connect the stepper motor with Stepper Motor Output port of the driver board, plug the external DC power into the Power In port.   Tip This driver board is suitable for 4-wire stepper motors. Depending on the stepper motor you use, the wiring color is different. We use the motor 24BYJ48 , the wiring is as shown in the table below: Pin Name Wire of Stepper Motor  Wire color(24BYJ48)  OUT1  one end of coil 1  Orange  OUT2  the other end of coil 1  Blue  OUT3  one end of coil 2  Pink  OUT4  the other end of coil 2  Yellow     Step 2. Connect the Grove - I2C Motor Driver (TB6612FNG) to port I2C of GroveBase Shield.  Step 3. Plug Grove - Base Shield into Seeeduino.  Step 4. Connect Seeeduino to PC via a USB cable.   Note Since the DC port and the stepper port are physically connected together, you can also use the two DC port to control your stepper motor. The connection diagram is as follows: Note If we don't have Grove Base Shield, We also can directly connect this module to Seeeduino as below.     Seeeduino Grove Cable  Grove ‐ I2C Motor Driver (TB6612FNG)  GND  Black  GND  5V or 3.3V  Red  VCC  SDA  White  SDA  SCL  Yellow  SCL  Software Attention If this is the first time you work with Arduino, we strongly recommend you to see Getting Started with Arduinobefore the start.  Step 1. Download the Grove_Motor_Driver_TB6612FNG Library from Github.  Step 2. Refer to How to install library to install library for Arduino.  Step 3. Restart the Arduino IDE. Open the default example, we provide two examples for you dc_motor: Demo for DC motor stepper_motor_2phase: Demo for 4-wire, 2phase stepper motor. You can open them in the following two ways(take the dc_motor for example)： 1. Open it directly in the Arduino IDE via the path: File → Examples → Grove - Motor Driver(TB6612FNG) → dc_motor. 2. Open it in your computer by click the dc_motor.ino which you can find in the folder XXXX\Arduino\libraries\Grove_Motor_Driver_TB6612FNG-     master\examples\dc_motor, XXXX is the location you installed the Arduino IDE.  Step 4. Upload the demo. If you do not know how to upload the code, please check How to upload code. Success If every thing goes well, when you power up the external power port, the motor will run.
