hi seon
could you already test the ESP32-S2 Beta IDF and these Toolchain with HTTP request "protocol" example / or Basic function for you?
also for interest - can you say, what (ESPRESSIF) PSRAM is soldered on the Modul / Board?
Is it 32M or 64M ( PSRAM32 / PSRAM64 )? also which SPI Flash? 32M / 64M / 128M .. ?
txs!
best wishes

Can it be answered now whether it has CAN bus? (It could not previously be answered, but the video suggested it may not).
