This print houses a single Adafruit QT PY board with USBC connector. The top snaps shut and has two button cutouts to allow you to press the reset / PIN9 button.
It has a small slit in the back for cables - I use it to wire in external BME280 sensors or you can use the QT STEMMA version for plugging in a stemma board
