THIS COMES WITH NO WARRANTY! BUILD, FLY, AND USE AT YOUR OWN RISK!

Build your own

Make sure to init the git submodule for the libraries in the kicad_misc directory by calling git submodule init && git submodule update. You will have to use a recent kicad version, i used the commit #efdfaeb when i designed this circuit board. Older versions will probably not work.

Questions

How big is the TinyFINITY PCB?

It measures 34.1 × 34.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the TinyFINITY use?

155 parts, built around the RTC6705, MIC5205YM5 and TS3A44159PW. 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 TinyFINITY KiCad files?

From the fishpepper/tinyFINITY repository on GitHub, at the commit this page was made from: the board is tinyFINITY.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the TinyFINITY design in my own project?

Its repository states no licence, so its author keeps all rights: ask fishpepper before reusing the design.
