More pictures
This board was prototyped and working, but there are still things to do
- Add configuration in the firmware for the two encoders.
- Add configuration in the firmware for the missing compatible layouts.
- Provide a BOM and POS file for assembly.
- Fix a bodge wire in the prototype.

Questions
How big is the WaveTheory PCB?
It measures 284.6 × 93.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WaveTheory use?
151 parts, built around the TP4056, USBLC6-2SC6 and AO3401A. 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 WaveTheory KiCad files?
From the quark-works/WaveTheory repository on GitHub, at the commit this page was made from: the board is PCB/WaveTheory.kicad_pcb and its schematic PCB/WaveTheory.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WaveTheory design in my own project?
Its repository states no licence, so its author keeps all rights: ask quark-works before reusing the design.
