A curated electronics kit built around the Adafruit CLUE board and PyLeap — Adafruit's app for wirelessly transferring code and assets from the Learn system directly to your device. No complicated setup or USB cable needed for programming once you're connected via Bluetooth.

The CLUE board packs a huge array of built-in sensors (temperature, humidity, pressure, light, colour, proximity, accelerometer, gyroscope, magnetometer, sound, and gesture) plus a 1.3" colour display. Combined with the included NeoPixel strip, micro servo, battery holder, and accessories, this kit is everything you need to dive into sensor projects, data logging, and Bluetooth-controlled builds.

Key Features

  • Adafruit CLUE BoardnRF52840 with Bluetooth LE, packed with built-in sensors and a 1.3" colour display
  • PyLeap Compatible – Wirelessly transfer code from Adafruit Learn guides to the board
  • NeoPixel LED Strip – 0.5m strip (60 LED/m) with alligator clips for easy connection
  • Micro Servo – For motion and actuation projects
  • Battery Powered – 3×AA holder with switch, JST connector, and belt clip
  • Clear Acrylic Case – Protective enclosure for the CLUE board

Ideal For

  • Learning CircuitPython and PyLeap
  • Sensor data logging and plotting
  • Bluetooth-controlled NeoPixel projects
  • Custom conference badges and wearables
  • STEM education and workshops

Resources

Jargon buster

Plain-language definitions for the technical terms used above.

alligator clip
An alligator clip is a spring-loaded metal clip used to make temporary electrical connections to wires, terminals or test points. It is useful for quick bench testing, but it is less secure than a screw terminal or locking connector.
CircuitPython
A beginner-friendly version of Python designed to run directly on microcontroller boards. If a product supports CircuitPython, you can often program it by copying code files onto the board rather than setting up a more complex toolchain.
Gyroscope
A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
LED
A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
magnetometer
A sensor that measures magnetic fields, often used to work out compass direction. It matters because nearby magnets, motors, or metal objects can affect readings and may require calibration.
NeoPixel
A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
nRF52840
The nRF52840 is a Nordic Semiconductor microcontroller commonly used in maker boards, especially where Bluetooth Low Energy is needed. Seeing it listed tells you the USB host software may support boards based on this chip.
servo
A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
