Hello all,
We would like to develop a small sensor as payload for the DJI Drones.
Therefore we want to use the ESP32-C3-MINI Controler (cause it is supported by the PSDK).

We are currently in the hardware design phase and there i have some questions:

In general: are there any wireing examples how the E-Port can be connected with the ESP32?
From my understanding the E-Port has two serial connections. One USB and one UART.
Is it possible to connect only the UART Port of the E-Port with the ESP32? The idea would be to use the USB port of the ESP32 for flashing and debugging.
In this case we would let the USB Port of the E-Port open.

The other possibility would be to connect the USB Port of the E-Port with the USB Port of the ESP32. From my understanding the ESP32 has two functionalties on this USB Port:
CDC-ACM (Communication Device Class - Abstract Control Model) and JTAG adapter functionality. So in this case the E-Port USB should be able to support CDC-ACM communication to be able to communicate with the ESP32.

(The UART port on both devices would not be used in this case)

Does someone has some ideas how this connection could be done in best way?

Thank you very much in advance!
