Adafruit CLUE

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.

Do you feel like you just don't have a CLUE? Well, we can help with that - get a CLUE here at the Maker Shed by picking up this sensor-packed development board. The clue has a small color screen and a lot of sensors. To make it compatible with existing projects, it's 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)
• Two A / B user buttons and one reset button
• Tons of sensors!
• ST Micro series 9-DoF motion - LSM6DS33 Accel/Gyro + LIS3MDL magnetometer
• APDS9960 Proximity, Light, Color, and Gesture Sensor
• PDM Microphone sound sensor
• SHT Humidity
• BMP280 temperature and barometric pressure/altitude
• RGB NeoPixel indicator LED
• 2 MB internal flash storage for data logging, images, fonts or CircuitPython code
• Buzzer/speaker for playing tones and beeps
• Two bright white LEDs in front for illumination / color sensing.
• Qwiic / STEMMA QT connector for adding more sensors, motor controllers, or displays over I2C. You can plug in GROVE I2C sensors by using an adapter cable.
• Programmable with Arduino IDE or CircuitPython
