Hello, I am making school project with ESP32. I want to power it with 5V adapter but I want to also be able to use USB port whenever I want to change something in code. I know I can't give power to ESP32 with USB while giving power to it with 5V and GND pins but I don't want to risk that I could forgot i have the ESP32 plugged in or someone else didn't know. I don't know if it is exactly called overvoltage protection but I hope you get the point from my description. So if someone has solution I'd love to hear it. Thanks.

Thank you for answering. And sorry for this stupid question. I thought mine ESP didn't have the diode so I wanted to make external circuit, but thanks to You I found out it has the diode.
