The schematic is not correct as this makes no sense at all -Oke doke - first, waveshare sent the correct schematic: https://www.waveshare.net/w/upload/0/06 ... er_Sch.pdf
So yeah - the linked schematic was for a different product - this appears to be correct ^^
The top or middle "5V" should presumably be "5V_IN" as per the earlier schematic.
It does however show a diode feeding VSYS from 5V_IN (regulator output) which is presumably what's powering the Pico W when the USB cable is disconnected or when VBUS via its diode is less than VSYS.
I am not convinced the Pico W is a fake or clone. Some suppliers show photos of Pico W boards silkscreened with a space, "Pico W (C) 2022", while others show no space "PicoW (C) 2022" - https://robosavvy.co.uk/raspberry-pi-pico-w.html
I have always disliked the way Raspberry Pi silently changes things without bumping revision identifiers because it leads people to suspect boards different to what they see in other photographs are fakes or clones when they most likely aren't.
I have no idea why the wireless module or anything else is overheating, what the Pico W is burning out. There seems to be no reason it should.
