## Description

This motor driver carrier board is a specially designed carrier for the UNIHIKER, featuring a tilted edge connector slot that provides the screen with the optimal viewing angle. It **integrates a dual DC motor drive** that can be powered separately, offering flexible power supply options including USB, DC head, and terminal block. The board also includes **onboard RGB lights and infrared transmission and reception functions**, enhancing its playability and versatility. It extends 10\*3Pin ports and 4\*I2C ports, supporting 5V I2C for stronger compatibility and making it highly expandable.

Additionally, all spare IOs are led out, and multiple indicator lights (for power, motor power, and motor signal) are included, making it convenient for debugging. The carrier can also power the UNIHIKER via a U-shaped USB adapter cable. In combination with DFRobot's powerful Gravity product system, this carrier opens up unlimited possibilities for creative and functional projects with the UNIHIKER.
