Questions

How big is the Hexx4 PCB?

It measures 50 × 34.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Hexx4 use?

34 parts, built around the ATTINY816-SN. 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 Hexx4 KiCad files?

From the mengstr/HexxDisps repository on GitHub, at the commit this page was made from: the board is Hexx4/Hexx4.kicad_pcb and its schematic Hexx2/Hexx2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Hexx4 design in my own project?

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