Questions
How big is the YM60JIS PCB PCB?
It measures 285.1 × 94.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the YM60JIS PCB use?
173 parts, built around the RP2040, W25Q16JVUXIQ, SMF05CT1G and XC6206P332MR. 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 YM60JIS PCB KiCad files?
From the ymkn/YM60JIS repository on GitHub, at the commit this page was made from: the board is KiCAD/PCB/YM60JIS_PCB.kicad_pcb and its schematic KiCAD/PCB/YM60JIS_PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the YM60JIS PCB design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
