The Adafruit nRF52840 has joined the growing list of CircuitPython compatible boards. It features a Cortex M4 chip with Bluetooth Low Energy. We've added BLE support to CircuitPython which makes it super simple to get started!

CircuitPython is Python that runs on microcontrollers. It's designed to lower the barrier for entry to learning programming and electronics. If you're new to CircuitPython, please check out the Welcome to CircuitPython guide to find out how to get started with CircuitPython.

CircuitPython, BLE and Bluefruit LE Connect

This guide is designed to help you get started with CircuitPython, the Adafruit nRF52840 and the Bluefruit LE Connect app.

First you'll learn some Bluetooth Low Energy Basics to help you understand what your CircuitPython code is doing.

There is a quick intro to the Adafruit Bluefruit LE Connect app with links to install it, and how to get to the controller interface.

Then you'll be provided a series of quick demos using CircuitPython, the Adafruit nRF52840, and the Bluefruit LE Connect app for mobile devices. You'll learn things like how to read a button press from the app's control pad interface, how to change the color of a NeoPixel, or how to read acceleration data from your mobile device.

Let's get started!
