Grove - I2C motor driver (L298N chip)

Grove - I2C motor driver

The Grove - I2C motor driver V1.3 can directly control stepper motors or DC motors. At its heart is a dual-channel H-bridge driver chip (L298N) that can handle currents of up to 2A per channel and is controlled by an Atmel ATmega8L that handles I2C communication. Both motors can be driven simultaneously, set to different speeds and directions. It can drive two 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 integrated 5V voltage regulator that can supply power to the I2C bus and e.g. an Arduino (selectable by jumper). All driver lines are protected against back EMF by diodes.

In contrast to the Grove I2C motor driver V1.2, the V1.3 enables users to control the stepper motor more easily. You no longer need to constantly control the stepper motors. Simply send a command to the V1.3 I2C motor driver to drive a stepper motor and it will act as your command, saving your Arduino resources and simplifying your code.

What is Grove?

Grove facilitates connection, experimentation and simplifies the prototyping process. No jumpers or soldering are required. More than 300 Grove modules have been developed to cover a wide range of applications and fulfill a variety of requirements. Not only the hardware is open source, but also the software. 

We offer various Grove shields to enable a connection to the Grove system with various microcontrollers. 

Scope of delivery:
