Circuit Playground Bluefruit features the nRF52840 Cortex M4 process, and has all those sensors you love from the previous Circuit Playgrounds: light, temperature, touch, and...sound! A built in PDM microphone makes this board perfect for trying out Tensorflow Lite for microcontrollers. This demo records audio via the mic, and then gives feedback on YES (green neopixels plus upwards tone), NO (red neopixels plus downwards tone). So far so good, this could be a handy board for learning the basics of machine learning. We committed our experiments to the Adafruit TFLite Micro Speed repo.
