Thanks for your thoughts, but just to clarify - the 'LILYGO T-Micro32' is not a dev board with USB chopped off. It's just a PICO-D4 chip and antenna. It's got no Serial2UART, no USB, no LDO or any power management, no battery management - it's got nothing. It's just a D4 SiP on a PCB with an antenna and an RF shield. No different to a WROOM-32 module.
You can't do anything with it unless you put it on a carrier PCB and add all of the other stuff yourself.
Seems to be a lot of confusion about what the Micro32 is and what it's not.
