power or esp32 by USB and VIN simultaneously is possible?

[matheussantana189]

i have an esp32 and i would like to know if i can connect it to the USB while it is feeding through the VIN input.
the ESP32 in question is the same as in the photo.
The point is that in the project I am using an external source and would like to monitor the serial via USB, is it possible?

It's a bit hard to say, as we don't know who built these modules... However, most of them have a diode between Vin and USB Vbus, making it possible to do what you want. You'd have to check if your module also has that.
