Do you feel like you just don’t have a CLUE? Well, we can help with that – get a CLUE here at Adafruit by picking up this sensor-packed development board. We wanted to build some projects that have a small screen and a lot of sensors. To make it compatible with existing projects, we 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.
While the CLUE looks a bit like a ‘bit it has totally redesigned-from-scratch technology:
Nordic nRF52840 Bluetooth LE processor – 1 MB of Flash, 256KB RAM, 64 MHz Cortex M4 processor
1.3″ 240×240 Color IPS TFT display for high resolution text and graphics
Power it from any 3-6V battery source (internal regulator and protection diodes)
Please note that at this time there is no MakeCode or Scratch support for the nRF52840 chipset (of course, we’d love to see MakeCode but there is no ETA when it may be added). While the CLUE is the same outline and we did our best to make the edge-connector pins match up, most cases for the ‘bit won’t fit the CLUE, and code may not be immediately compatible without adjustment, especially since only Arduino and CircuitPython are supported at this time.
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. Why did we call it CLUE? Check out our post!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
