If we look at the top left of the schematic diagram found here:

It would appear that we can supply an external source of 5V. This appears to enter a voltage regulator that drops the output to 3.3V.

What generates the 5V you use and how do you connect it to the board? The ESP32 has somewhat high requirements for a power source (>=500mA) and not all power sources can deliver that.
