Overview

It's now easier than ever to build your own rover bot with Bluetooth Low Energy (BLE) control! Use the Adafruit Bluefruit app on an Android or iOS device to drive it and change the underlighting colors!

All thanks to CircuitPython, the coding is simple and straightforward. You can even add accessories or assign the buttons to different functions. There are lots of opportunities for modifications on the project, too, including accessing your phone's accelerometer for tilt control!

You'll use the powerful Feather nRF52840 Express, the Crickit robotics platform, a beautiful purple aluminum chassis, motors, wheels, a 24 NeoPixel ring and a few other parts to build this one-of-a-kind rover.
