Well, we can help with that - get a CLUE here at Adafruit by picking up this sensor-packed development board.\u003c\/p\u003e\n\u003cp\u003eWe 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.\u003c\/p\u003e\n\u003cp\u003eWhile the CLUE looks a bit like a 'bit it has totally redesigned-from-scratch technology:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNordic nRF52840 Bluetooth LE processor\u003c\/strong\u003e - 1 MB of Flash, 256KB RAM, 64 MHz Cortex M4 processor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1.3″ 240×240 Color IPS TFT display\u003c\/strong\u003e for high resolution text and graphics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower it from any 3-6V battery source\u003c\/strong\u003e (internal regulator and protection diodes)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo A \/ B user buttons\u003c\/strong\u003e and one reset button\u003c\/li\u003e\n\u003cli\u003eTons of sensors!\n\u003cul\u003e\n\u003cli\u003eST Micro series 9-DoF motion -\u003cspan\u003e \u003c\/span\u003eLSM6DS3TR Accel\/Gyro\u003cspan\u003e \u003c\/span\u003e+\u003cspan\u003e \u003c\/span\u003eLIS3MDL\u003cspan\u003e \u003c\/span\u003emagnetometer\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAPDS9960 Proximity, Light, Color, and Gesture Sensor\u003c\/li\u003e\n\u003cli\u003ePDM Microphone sound sensor\u003c\/li\u003e\n\u003cli\u003eSHT Humidity\u003c\/li\u003e\n\u003cli\u003eBMP280 temperature and barometric pressure\/altitude\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRGB NeoPixel\u003c\/strong\u003e indicator LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2 MB internal flash storage\u003c\/strong\u003e for datalogging, images, fonts or CircuitPython code\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuzzer\/speaker\u003c\/strong\u003e for playing tones and beeps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo bright white LEDs \u003c\/strong\u003ein front for illumination \/ color sensing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQwiic \/ STEMMA QT connector\u003c\/strong\u003e for adding more sensors, motor controllers, or displays over I2C.

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 wont fit the CLUE, and code may not be immediately compatible without adjustment, especially since only Arduino and CircuitPython are supported at this time.\u003c\/p\u003e\n\u003cp\u003eThe 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?
