Adafruit CLUE - nRF52840 Express with Bluetooth LE

This board has been designed to fix the problem when you want lots of sensors and a screen within your project. To make it compatible with existing projects, they made it the same shape and size as the BBC micro:bit and with the same edge-connector on the bottom with 5 big pads so it will fit into your existing robot kit or 'bit add-on.

The CLUE is designed for projects that use a ton of sensors - and they're all built-in! So you can start exploring your world, measuring, logging, and learning. You can transmit data over Bluetooth to a computer or mobile device for data plotting and logging, or save it to the built-in storage.

Please Note

• At this time there is no MakeCode or Scratch support for the nRF52840 chipset.
• While the CLUE is the same outline the edge-connector pins match up (to the best of Adafruits ability), most cases for the 'bit won't fit the CLUE, and code may not be immediately compatible without adjustments, especially since only Arduino and CircuitPython are supported at this time.

• Nordic nRF52840 Bluetooth LE processor - 1 MB of Flash, 256KB RAM, 64 MHz Cortex M4 processor
