power supply options with output 5V
Posted: Tue Feb 11, 2020 7:20 pm
I have powered Wemos Lolin 32 ESP32 board via power supply (not USB) with 3,3V. I understand USB power input would be 5V, but on power input (which is separate connector) I need to supply 3,3V. Here is my board:

Question, is it possible to use 5V connector (left side second bottom one, next to GND) to get 5V out which I need to power relays? There is 5V connector on this board, however it does not provide 5V in my case. Should I enable it via micropython command? Or is it only available if board is powered via USB 5V input?
I have 5V relays ant those work only sometimes when powered with 3,3V, so need to find another solution.
