Hi, I'm trying to knock out a project with my new pico for May. I need to log GPS co-ordinates for about 9 hours for 3 days. I can charge between that. Then offload all this data to a pc.
I've been reading some docs and I think I'll have to write this to an SD card. Would another option be to use a typed array in RAM and use save() every now and then so I don't have to panic about losing power and all the data?
I see the sleep current draw advertised but what's the peak power so I can make a worst case estimate to size the battery I'm buying (factoring in the GPS unit naturally). I assume the pico will sleep as best it can for me? I'm used to the arduino and I'd have to program in the sleep calls.
Is there any way to put a female USB-A on a pendrive and get the pico to write to that? Just trying to get out of doing the SD card bit of I can.
