      Are https://github.com/Xinyuan-LilyGO/LilyGo-LoRa-Series/blob/master/schematic/T3_V1.6.1.pdf the correct schematics for the pax counter board? I'm having trouble understanding where VBUS comes from? In the LED box (top drawing RH side) it's shown as driving the green led. In the unlabelled box (bottom drawing bottom left hand corner) its shown as different from +5v (with a 23v Schottky between them). But I can't find any other reference to it so where is it derived from?

        I don't understand what is your problem? VBUS input source is MicroUSB, D1 and Q1 are battery input and VBUS selection circuit
