SparkFun Thing Plus - ESP32 WROOM and DMX Shield Power Question

Development Boards ESP32

Hi,

I’m trying to find out if the SparkFun Thing Plus - ESP32 WROOM (USB-C) is safe to have connected to both 5V on the SparkFun ESP32 DMX to LED Shield as well as USB-C. I’d like to be able to program/debug the ESP32 while connected to all the peripherals but from what I can find the 5V connections are linked and I don’t want to damage my computer’s USB connection.

Any help is appreciated, thanks!

I’m not 100% sure whether that will backfeed voltage or not, but you could just wire them together (instead of stacking the 2), powered separately, and debug as-described that way…and then use one power source later/after, or snip the V pin/leg on the WROOM so they aren’t connected when stacked
