I’m trying to do a small weather station project with an Argon and a 1000mah LiPoly battery. That part is relatively easy. However, given that the Argon can only STOP, not HIBERNATE for the RTC change, I have some concerns about my peripherals.
In STOP, does the 3v3 line turn off from the Argon? I’m using the 3v3 output to power my two thermometers, and I believe in HIBERNATE, that line would turn off. I’m still waiting for my solar assembly to show up so I can’t test, but I thought I would ask. Should I put a NPN in front of the power to the thermometers, or will it work without vampire draws if connected directly to 3v3?
Also, I don’t see any figures for how much current is consumed by the device in STOP versus HIBERNATE. Is that available somewhere and I missed it? I have been reading a lot of the posts about sleep issues with Argon/GEN3 devices, and it looks like if you manually turn WiFi off, the sleep current goes below a milliamp, but I’m curious if there are any actual measurements that can be found?
