Maybe OTG is superseded? USB C dual role port is the way to go, but needs a 25c chip and software support to make it work. FUSB30x FTW :)

I will order Beetle ESP32-C3 this one should have direct USB/UART/JTAG pins on the USB-C connector :-) I have ordered ESP32-S2 as it has USB OTG. I really miss RISC-V MCU with USB Device/OTG.. ESP32-C6 would be perfect if it only had this (it has WiFi + BLE + Mesh already) :-) Is there any chance that Espressif releases ESP32-C6 + USB OTG anytime soon? :-) C6 is like C3, only USB Serial/JTAG, not real USB OTG support: https://www.espressif.com/sites/default/files/documentation/esp32-c6_technical_reference_manual_en.pdf BR, Alan
