I am trying to run an air quality sensor on this board, and chose it because of the display and integrated battery support.
My PMS5003 requires 5V power for its fan, and since the board diagrams show the power pin as 5V not Vin, I thought that it would provide 5V even on battery power. However, when I disconnect USB and run on battery, that sensor seems to shut down. Does that 5V pin drop down to battery voltage?
