Description

An Atmel ATmega8L handles the I2C communication. Both motors can be driven simultaneously while set to a different speeds and directions. This can power two brushed DC motors or one 4-wire two-phase stepper motor.  A 6V to 15V power supply is required to power the motor.  An onboard 5V voltage regulator powers the I2C bus (selectable by jumper). All driver lines are diode protected from back EMF.

The software interface is easy-to-use and is designed to get you up and running in no time. It features a LED for power and four LED’s to indicate 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.
