Setting the jumper wrong causes the USB to TTL adapter to set itself to neither 3.3v nor 5v.
I didn't measure what voltage it was supplying, but I'd guess it resulted in at least 2 amps. It melted the Dupont connectors together.
Surprisingly, it didn't destroy the ESP32 that I was trying to program.

Yeah, both the ESP32 and the USB-TTL converter work after taking enough amps to melt the plastic!

What’s it soposta do?

It lets the computer communicate with the ESP32 using the computer's USB port and the ESP32's TX and RX lines.
