Sparkfun ESP32-C6 Power from either USB or PCB regulator

Development Boards ESP32

My question is regarding power from either USB or external 5 volt regulator. Can I plug in and still program via the USB-C plug and still have the board powered by an external 5 VDC regulator.

My design is that the main power is coming from a 12VDC supply because I am using a 12volt servo. I want to use just one supply so that 12 volts will be regulated down to 5 volts then connected to the ESP32 to power it. But, if I want to program the controller I will plug in the USB cable, will this work since both USB and external regulator are supplying 5 volts and will be in battle with each other? On the Teensy boards there was a jumper that had to be cut if you wanted to do this.

Thank you.

It looks like there are diodes on both paths (usb & batt) https://docs.sparkfun.com/SparkFun_Thing_Plus_ESP32_C6/assets/board_files/Thing_Plus_ESP32_C6.pdf

so I think it should be fine…but you can always make your life easier by simply disconnecting the board’s power/gnd from the 12v source when programming and re-hook it up after done testing

You might have to disable the SHLD jumper as well, depending Hardware Overview - SparkFun Thing Plus - ESP32-C6
