Research direction
No repository files, tests, or entry points are mentioned. The issue is an open-ended discussion of hardware requirements for an ESP32 AirTag-like board, so completion criteria and implementation scope would need to be established first.

Description
Hi all, since I haven't seen any type of esp32 based boards by the usual suspects (ttgo, lilygo, lolin) that would fit my personal requirements for an AirTag-like board my question is: What board are you guys using beyond development-boards?
Technically it could just come in the form of a battery holder that routes out the programming header from a micro32 board.
My ideal board would:
- run on CR2032 (maybe larger) cell
- No WiFi RF startup shouldn't be a problem
- Not sure how long the cell can provide up to 2.5V under load
- be based on
- led-less micro esp32 module LilyGo Micro 32 comes to mind
- OR esp32 directly on board (much more effort to design specific board)
- ADC for voltage readout
- have header or test-pads (VCC, GND, IO0, TX, RX) to connect to programming base
Since this is not much, I am sure I forgot a lot... What do you guys think? Any dev board out there I am missing (round design? battery management included?)
Thanks for any ideas 😊
