TODO:
- WiFi improvements
- Add config keys for at least 3 WiFi networks and SSIDs
- Attempt to join each in series for 20 seconds at a time
- If all three fail, become AP instead
- Add option to go straight to AP mode
- Add ADC measurement and recording for battery voltage
- Defaults for config

Questions
How big is the Bmchimes PCB?
It measures 63.5 × 50.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Bmchimes use?
28 parts, built around the 74HC7014D. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Bmchimes KiCad files?
From the xunil/bmchimes repository on GitHub, at the commit this page was made from: the board is bmchimes.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Bmchimes design in my own project?
Its repository states no licence, so its author keeps all rights: ask xunil before reusing the design.
