Schematics and PCB for the OTuner - optical guitar tuner, which uses stroboscopic effect instead of sound.
The project was done as a part of Principles of Computer Organization course at UCU in association with mentors from Renesas company.
The main branch contains files that ended up as a final version for the student project and the dev branch contains files for future development as a standalone project.

Questions
How big is the OTunerPCB PCB?
It measures 56.1 × 100.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the OTunerPCB use?
50 parts, built around the MP1584EN and TP4056. 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 OTunerPCB KiCad files?
From the myrimur/OTunerPCB repository on GitHub, at the commit this page was made from: the board is 112.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the OTunerPCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask myrimur before reusing the design.
