Questions

How big is the SplishSplash PCB?

It measures 284.2 × 102.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SplishSplash use?

102 parts. 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 SplishSplash KiCad files?

From the anshulsamudayanan/SplishSplash repository on GitHub, at the commit this page was made from: the board is PCB Files/SplishSplash.kicad_pcb and its schematic PCB Files/SplishSplash.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SplishSplash design in my own project?

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