I have a project on my desk that started as a response to a line in the Adafruit docs for their RP2040 based MacroPad

     It is not possible to add BLE or WiFi at this time to the MacroPad.

Oh yeah, really? There is a port hanging off the side that can be reconfigured for UART, are you sure Adafruit, what if I add an ESP32?
