    Description

    Its heart is a dual channel H-bridge driver chip that can handle current up to 2A per channel, controlled by an Atmel ATmega8L which handles the I2C communication with for example an Arduino. Both motors can be driven simultaneously while set to a different speed and direction. It can power two brushed DC motors or one 4-wire two-phase stepper motor. It requires a 6V to 15V power supply to power the motor and has an onboard 5V voltage regulator which can power the I2C bus (selectable by jumper). All driver lines are diode protected from back EMF.

    The easy software interface is not the only easy-to-use feature because the I2C motor driver is designed to get you up and running in notime. It features a LED for power and four LED's to indicate if and to which direction each motor is running. Screw terminals facilitate motor and power connections, and the GROVE system plug and I2C interface enables you to daisy-chain the driver with many other devices.

    HI -

    One Grove base shield has 4 I2C slots. Each slot can also be extended with Grove I2C Hub.

    Can anyone tell me any limitations to extend I2C slot on one base shield?
    How many I2C Motor Driver can be connected on one base shield?

    Yes! worked fine. Pay attention to the uart interface extended in the board, notice the distance between GPRS Shield and UNO, do not short to ground.

    I2C is supposed to support 255 devices. This board only has 15 possible different addresses. You will also notice that often, different I2C devices can have the same address and therefore cannot be used simultaneously. The I2C addresses are purchased and registered, so manufacturers sometimes give that same address to more than one of their products rather than purchasing a second address.Communication timing of the signal is crucial when sending I2C commands. Keeping your cables short, also helps. I had problems getting an I2C circular LED device to work with an UNO board. I used the same program logic with another board that had a faster processor and it worked perfect.

    Hi, can anybody suggest how I might be able to add limit switch(es) or encoder signal inputs to this board to indicate to the Atmega that the motor has reached a desired position? Thanks, Dion.

    Dear.If you want to control motor output,encoder can't do that.You need Radio Port Control Unit(like bluetooth or RF) ,which are connected to your arduino.If you have interesting,please sent e-mail to us.

    You do not have to connect your limit switches to the motor driver board. Connect the limit switches to your main board using a digital input for each limit switch. The I2C board could not notify the controller that the limit switch has been closed. The motor driver board only listens for it's address and then executes the commands that are given to it by the main controller board.

    Hi,

    I bought an AVRISP USB ISP programmer to update the firmware of the ???Grove ??“ I2C Motor driver??? using the .HEX file in the WikI website (mega8motorDriver092.hex). It does not seem to have made any difference, I am not convinced that this

    The external power supply is ranging from 7V to 15V.

    Hi Ernie, because the firmware is writed 2 years ago that I can not find the source code .I can make sure that the v0.9b and v1.1 has the same firmware .If it confilct with other device , you can try to change the I2C address of Motor driver.

    Processor speed of your main board is important to get the signal timing correct for your computer to be able to communicate well. Make sure you are using the correct I2C address, as well.

    Hello - I am using a DC motor and writing speed (0xFF) and direction (0b0010) to turn full power to MotorA (M1). When I monitor the negative side of the output I still see ~0.7V instead of 0V. The M+ side shows 5.5V. I am supplying 6.8V to the board

    It can't be power by 12V adapter,it will damage the Shield .

    Hi there , the GPRS shield only used D7/D8(software serial) or D1/D0(hardware serial) , depend on which serial you used. And the other pins is unused ,we don't do the more explore for RTC , you can read the SIM900 datasheet about it.
