user86102: I'm putting an Espressif ESP32-S2 Dev KitM-1 into a project box. The box will have 12VDC power and a 5V buck converter for the Dev Kit.
Do I need to use the USB port to power the Dev Kit or can I directly wire 5VDC to the 5V pin (and ground, of course) to power it?

user37622: The official documentation has

Power Supply Options
There are three mutually exclusive ways to provide power to the board:

Micro-USB Port, default power supply
5V and GND pin headers
3V3 and GND pin headers
