Introduction
The Grove - I2C Motor Driver V1.3 (latest version) can directly control Stepper Motor or DC Motor. Its heart
is a dual channel H-bridge driver chip
（
L298N
）
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 and the Arduino(selectable by
jumper). All driver lines are protected by diodes from back-EMF.
, the V1.3 enables users to control the stepper more easily.
You do not need to control the steppers all the time anymore, simply send a command to I2C motor driver
V1.3 to drive a stepper, and it will act as your command, which would save your Arduino resource and
simplify your code.
Cautions: The board will be very hot while operating over 1Amps. Do keep off your hands!
