Hi folks!
So I'm looking into the following, but having a very hard time finding any (remotely) definitive answers.
For my smart home, I'm looking to integrate more and more sensors that can relay all sorts of information. Most of these sensors I create myself using ESP32's and the like (probably also the Raspberry Pico W released today) and that's all working fine. What would really help for flexibility though, is to get rid of the dependency on wall power.
What I'd like is a battery solution for these microcontrollers that I can charge every month or so over either USB-C or micro-USB.
Problem is, wherever I look, solution seem mostly focused on "whatever you're doing, you're probably doing wrong, because batteries and charging circuits are HARD".
Therefore I'm turning to the true experts, you!
So, the actual question is, what would I need in order to power an ESP32 (or anything using 3.3V) from rechargeable batteries, that I can also continue to use while charging?
At this point I'd almost prefer an off the shelve solution that I can just solder onto the microprocessor, but I'm actually also interested in which components I'd need to find, the caveats in wiring/usage/etc. I've seen 18650 batteries mentioned as a good option, but I've also seen people advocating for LiPo batteries and truth be told, I'm just extremely lost at this point
Thanks in advance for your time!
