Questions

How big is the Type e PCB?

It measures 140.5 × 30 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Type e use?

16 parts, built around the 74HC165D. 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 Type e KiCad files?

From the google/mozc-devices repository on GitHub, at the commit this page was made from: the board is mozc-bar/board/type-e/type-e.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Type e design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
