Waffle Keyboard

Waffle is a 6x5 ortholinear keyboard which uses TRRS connectors to form a split keyboard when two are connected. It is designed to be used with an Elite-C or Elite-Pi microcontroller. There are currently two revisions, descriptions are available on the releases page.

This keyboard is designed in KiCad. Footprints are based off of the following libraries:

Questions

How big is the Waffle PCB?

It measures 110.5 × 91.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Waffle use?

71 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 Waffle KiCad files?

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

Can I use the Waffle design in my own project?

Its repository publishes it under the MPL-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).
