This board is a clone of the DFRobot Romeo V2.2 board. The board provides an all-in-one solution for driving motors and handling sensors. It is based on the Arduino Leonardo ATmega32U4 chip and should be programmed using the Arduino Leonardo board selection in the IDE.
This platform packs a lot into a small space. It can be a handy platform, but also a bit overwhelming if you are new to Arduino. Be sure to pay particular attention when hooking up power. To make things easier, we download and test using the software below and leave it in the board when you get it.
