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.

Can some provide schematics for i2c motor driver v1.3
It is sold as a shield , sure that it work it is .
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 .
Is this driver (v1.2) work with Arduino Yun??
I am using the XU3 and programming in C++ with Geany , are there any libraries I can use to easily control the motors?
Thanks for your advice,it is really a good opinion.I will feedback to our designer,and consider it.
I am using the RaspberryPI and programming in C++ with Geany , are there any libraries I can use to easily control the motors?
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.
I2C bus appears to hang with Arduino Nano 3.1
I have 6 SeeedStudio i2c Motor Controllers V1.3 all connected in parallel to the 5v, GND, A4 and A5 pins using 2.2k pull up resistors to 5v on the Nano 3.1
I have set the addresses on all Motor Contro
The I2C pins dont seem to be used. the datasheet for the sim900 says you need a special firmware to use I2C, so these dont seem to be needed on this shield.
Update. I have all Motor Controllers working on the same i2c bus so I can essentially run 6 steppers using the old school step by step commands via the i2c bus... This is a step in the right direction, but not what I bought the boards for... They ar
Hi, Does this work with the Raspberry Pi? If so, what things are needed to be done (if at all) differently to the Arduino?
Why are the I2C pins connected? they seem to stop other I2C devices working as the GPRS stops the I2C communication. Can I cut the traces on the GPRS board that connect the I2C to the SIM900?
I'm sorry we have not test it with Pi, please leave your feedback on the website: http://support.seeedstudio.com....
@Simon Barrett: Hi, if you google"I2C interface raspberry", you'll get a lot of links. Conclusion: It will work fine at Raspberry Pi.
(not tested it by myself, and Beaglebone are on my todo-list)
You ever find any python examples? would also love to see some
This is bad advice sadly, as it does not seem to work out of the box with the raspberry pi.
So I'm using a Beaglebone Black, and I have this connected to the i2c-2 bus. All it does is have all 4 LEDs light up and does not respond to any i2c communications. Is there anything I can do to debug this?
The GPRS Shield worked if the mother board supply at least 450mA current. We suggest using an external power supply to make the Shield work stable.
All programs on the wiki of I2C motor driver are designed for Arduino/Seeeduino, but if using it with Beaglebone Black, you need make libraries for it by yourself.
It's really incredible that Seeedstudio sells a Beaglebone Cape but then gives zero support for it's products.
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.
Hi, I want to connect a stepper with 1.4A/phase and 3.08VDC to V1.3b of the board. The GPRS Shield can be supply by extra power, due to the voltage tolerance ability of 470uF capacitor, the maximum supply voltage is limited at DC5V. We will expand the voltage range in future.
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".
