I naively hoped I’d get long battery life out of the CRC2032 batteries, but seem to hit the wall at about 2 weeks (or less). Since I’m trying to monitor my garage doors, I’m hoping to get at least a year without worrying about changing batteries. It could be added to the New Years Day list! Otherwise, I should simply use Photons instead.
If I want to power my BluzDKs with 2 AA batteries, do I simply wire them (in series) to 3.3 and Gnd?
I’m wondering if there’s availability of a shield with female headers on the top for the BluzDK and room for 2 AA batteries on the bottom. Before I quickly design a simple board like this, I wanted to check for availability–it seems so obvious.
