Techincal Notes
The wiring on the right side is kinda crazy because I didn't really know what I was doing in KiCad. Here's the reference I used when writing the firmware.

Questions
How big is the Spectrogram right PCB?
It measures 159.5 × 94.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spectrogram right use?
90 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 Spectrogram right KiCad files?
From the jakekyee/keybaord repository on GitHub, at the commit this page was made from: the board is working/spectrogram-right/spectrogram-right.kicad_pcb and its schematic working/platestuff/platestuff.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spectrogram right design in my own project?
Its repository states no licence, so its author keeps all rights: ask jakekyee before reusing the design.
