QTY:

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.

Features

  • Grove Compatiple
  • I2C Interface
  • Adjustable motor speed and rotation direction
  • Changable slave address by hardware

Interface Function

I2CMotorDriver-1.jpg
78M05 IC: 5v voltage regulator
L298 IC: dual full bridge driver
Atmega8 IC: Control Motor Rotate.
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 are used. Use jumper if 5v should be supplied to the I2C bus.
