The FireBeetle 8266 module shuts down the power for the USB serial chip when running on battery, which is optimal for bringing the current consumption down when in sleep mode. I noticed on the schematics that for the FireBeetle ESP32 this feature has been removed. I don't see any other measure which cuts the power for the USB serial chip. Is that intentional or is there an error on the schematic? I don't see how the power can be reduced to the claimed 10 µA when the CH340 continues to draw at least 90 µA.
