README
README.mdSandbox for electronics projects
This is my personal stash of small electronics projects, usually written using TinyGo.
I won't guarantee anything about it. All I can say is that it did work for me at some point and I like sharing what I made. Many things are written once and then mostly forgotten so I probably won't provide any support for any of the code.
License
Feel free to use this code however you wish (in other words, you can treat it as public domain). Especially for small parts I won't mind if you just copy it in your project. For larger pieces of code or if you copy a project entirely, I would appreciate attribution somewhere (but it's not required).
If you prefer having an actual license for legal reasons, you can use the MIT license - but again, the code is public domain so no need to actually use this:

Questions
How big is the Badge PCB?
It measures 50 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Badge use?
76 parts, built around the DMN2990UFA-7B, CR2032 and RB520S-30. 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 Badge KiCad files?
From the aykevl/things repository on GitHub, at the commit this page was made from: the board is badge-v1/badge.kicad_pcb and its schematic amulet-supercap/amulet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Badge design in my own project?
Its repository states no licence, so its author keeps all rights: ask aykevl before reusing the design.
