allisonlittle electronics question that is surprisingly tough to web search: i have a microcontroller dev board (pico 2) where one of the gpio pins is stuck at ground. i don't mean that it always reads as low—i mean my multimeter beeps continuity between the pin and ground when the device isn't even powered. is this a plausible failure mode for a gpio pin (say if i accidentally fried it), or is it more likely to be a bad/weird solder job on the headers, or...?
