* The +1V8_OUT pin is to connect an external capacitor to the module internal SPI flash and PSRAM for a more robust VDD_SPI supply. This pin should not be connected to any external circuits that may draw more than 20mA. Voltage of this pin will vary in module light sleep mode and approach zero in module deep sleep mode.
