Questions
How big is the Syokkenki2-2 PCB?
It measures 125 × 52 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Syokkenki2-2 use?
116 parts, built around the ESP32-S3R8, DRV8833PW, TCRT5000L and 74HC154PW,118-JSM. 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 Syokkenki2-2 KiCad files?
From the sakufff/future-ticket-machine repository on GitHub, at the commit this page was made from: the board is KiCad/syokkenki2/syokkenki2-2/syokkenki2-2.kicad_pcb and its schematic KiCad/syokkenki2/mosfet/mosfet.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Syokkenki2-2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask sakufff before reusing the design.
