Grove - I2C Motor Driver

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.

Specifications:

- Default address: 0x28
- Grove compatible
- I2C interface
- Changable slave address
- Speed control: proportional 8-bit
- Number of channels: 2
- Maximum output per channel: 0.7A
- Maximum Total current: 1.4A
- Input/output voltage on I2C bus[1]: 5v
- Input voltage on screw terminals: 6v-15v

[1] NOTE: Input voltage on screw terminals is regulated to 5v and connected to I2C +5v via a jumper (J4). Remove jumper if both external power via the screw terminals and power via the I2C header is used. Use jumper if 5v should be supplied to the I2C bus.

Application Ideas:

This motor driver can be used to drive any brushed electronic motor as long as it doesn't consume more than 2A at 5v. Two motors can be driven simultaneously while set to a different speed and direction. The speed can be set fully proportional and is controlled by the ATmega8 on the board using PWM. It is set by I2C commands sent from e.g. an Arduino. It is perfect for applications like robots, homebuilt RC cars, case fans, high power LED illumination or any other project that involves proportional load control.
