We wanted to build some projects that have a small screen and a lot of sensors. This board has a 1.3″ 240×240 IPS TFT display, two buttons, and a ton of sensors:
LSM series 9-DoF motion - LSM6DS33 Accel/Gyro + LIS3MDL magnetometer APDS9960 Proximity, Light, RGB, and Gesture Sensor PDM Microphone sound sensor Humidity, temperature and barometric environmental sensing There’s a Qwiic / STEMMA QT connector for adding more sensors, like PM2.5 air quality and others that were too big to fit on the board.
We’ll be primarily using CircuitPython for programming it, but it will also work in Arduino. And of course, we’d love to see MakeCode on it!
After designing it, the board was close enough to micro:bit-shape-size that we moved a few parts to make it fit in micro:bit robots and some projects – the nrf52840 is a big upgrade chip and can do stuff like Tensorflow Lite for Microcontrollers, BLE central and peripheral, and more.

This is the latest stable release of CircuitPython that will work with the CLUE NRF52840 Express.

This is the latest unstable release of CircuitPython that will work with the CLUE NRF52840 Express.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
