Funguje bezproblemove jak v USB, tak v OTG modu. Pro ty co radeji programuji v Pythonu nezli v C/C++ (Arduinu), je mozne nahrat MicroPython (ci CircuitPython) image. Trochu podrobnejsi navod jak na to naleznete zde:

Posledni python image lze stahnout zde:
https://micropython.org/download/ESP32_S2_WROVER/
Je take mozne nainstalovat CircuitPython, viz tato stranka (ozkouseno):

Vyhodou oproti klasickemu ESP32 je pristup k celemu obsahu SPI-RAM (V pripade teto desky to je 8MB. Neni zde omezeni na 4MB). Lze tedy pomerne pohodlne provozovat treba s ruznymi typy displeju, ktere vyzaduji implementaci frame bufferu.
Za mne mohu doporucit jako zajimavou alternativu ke klasicke ESP32.
