Questions
How big is the Tuner PCB?
It measures 48.3 × 40.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Tuner use?
46 parts, built around the NE5532 and AMS1117-3.3. 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 Tuner KiCad files?
From the WilliamLim781/PCB_practice repository on GitHub, at the commit this page was made from: the board is Tuner/Tuner.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tuner design in my own project?
Its repository states no licence, so its author keeps all rights: ask WilliamLim781 before reusing the design.
