Questions

How big is the Split56 PCB?

It measures 139.2 × 82 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Split56 use?

54 parts, built around the TCA9555PWR(UMW). 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 Split56 KiCad files?

From the Biacco42/split56 repository on GitHub, at the commit this page was made from: the board is split56/split56.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Split56 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
