Re: Hardware SPI Problem

I have not spent much time with the ESP32-CAM board, but the schematics show the SDCARD using pins 12, 13, and 14 (and others) for the SDMMC interface. Could that be causing issues with the hardware SPI?

Re: Display issues on the TTGO T-watch S76G (GPS + LoRa version)

Re: Can't flash an ESP32-S2

Given that the chip supports USB natively, why have Espressif implemented a USB-UART bridge? The native USB has some limitations (https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/api-guides/usb-otg-console.html) that could be annoying during development.
