Portability

Would it be possible to use this on an ESP32-C2 or similar? It has the needed bluetooth and memory and so on, as far as I can see, and it's tighly integrated and indeed cheap (from around $2 a piece)

Answering myself here, the ESP32-C2 doesn't support bluetooth classic, which is needed. It would, however, be nice to use an old ESP32-WROOM instead of the teensy.
