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.

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?
Hi, I want to connect a stepper with 1.4A/phase and 3.08VDC to V1.3b of the board.
The table in your documentation tells me the supply voltage is 6-15V with max. 0.5A per channel. But the description says"can handle current up to 2A per channel".
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.
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
Can some provide schematics for i2c motor driver v1.3
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
Is this driver (v1.2) work with Arduino Yun??
