So my followup question is: I have a few of these, can I do anything with them once I'm done with the test? Hook up to the headers and reprogram? What about the Binax test? Or any of the other "connected" ones?
Basically all those nRF5x products are Arduino compatible AirTags with a battery included. IIRC they also have an imprecise but low power, chip integral temperature gauge. Maybe a wireless interval thermometer might be a good start?
Yea I saw somewhere airtags are just Nordic chips? Kind of surprised because the airpod w1/h1 chips aren’t
I would guess either better margins or better low power performance for better battery longevity in the nRF 52.
Binax is just some cardboard and a strip, no chips.
