Adafruit CLUE - nRF52840 Express with Bluetooth® LE

Designed to integrate seamlessly into existing projects, this sensor-packed development board matches the dimensions and connector type of the BBC micro:bit. It features the Nordic nRF52840 Bluetooth® LE processor with 1 MB Flash and a 256KB RAM, supporting complex computations and data handling.

Boasting a 1.3″ 240×240 Color IPS TFT display, it provides high-resolution text and graphics. Power versatility is ensured with support for 3-6V battery sources. User interface options include two A/B buttons and a reset button.

A suite of sensors offers advanced capabilities: 9-DoF motion sensors, proximity, light, color, gesture detection, a microphone, and environmental sensors measure humidity, temperature, and pressure.

The board includes 2 MB internal flash storage for data logging and is programmable using Arduino IDE or CircuitPython. Despite differences from the BBC micro:bit, this board opens up new avenues for data exploration and project development.
