Testing out the TensorFlow micro speech demo on Adafruit CLUE (video). Only took us a few minutes to compile our TF Lite micro demo from the Circuit Playground Bluefruit over onto the CLUE board. It uses the same nRF52840 chipset and PDM microphone – worked well out of the box! With all the sensors on CLUE it will make for a good platform to try out various sensor-learning projects!

What is CLUE?

From Adafruit Top Secret! December 24, 2019 (video). Get a clue! ..

we wanted to build some projects that have a small screen and a lot of sensors. this board has a 1.3″ 240×240 ips tft display, two buttons, and a ton of sensors:

lsm series 9 dof motion, apds9960 light/color/proximity, pdm microphone, humidity, temperature and barometric environmental sensing.

there’s a qwiic/stemmaqt connector for adding more sensors like pm2.5 air quality and others that were too big to fit on the board.

we’ll be primarily using circuitpython for programming it, but it will also work in arduino. and of course, we’d love to see makecode on it!

after designing it, the board was close enough to micro:bit-shape-size that we moved a few parts to make it fit in micro:bit robots and some projects – the nrf52840 is a big upgrade chip and can do stuff like tensorflow lite for microcontrollers, ble central and peripheral, and more.
