README
docs/assets/projects/README.mdProject showcase exports
These PNGs are unmodified exports copied from Jeremy's local 555 Pulse Generator, Maize Factory, and Access Terminal S3 projects for the public Jenga showcase. They show design artifacts, not fabricated or certified hardware. The terminal remains subject to engineering review, as described on the website. The Maize Factory project is represented by its power and control schematics only.
The GLB files are actual exported 3D assemblies, not turntable videos. Native schematic and PCB files are offered for inspection. Native boards can reference project-specific external models or libraries; the self-contained GLB is the portable visual assembly. Downloads are development examples, not manufacturing-approved designs.

Questions
How big is the Terminal PCB?
It measures 160 × 180 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Terminal use?
48 parts, built around the ESP32-S3-WROOM-1-N8R8 and BSS138. 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 Terminal KiCad files?
From the JeremyKariukicodesnow/Jenga repository on GitHub, at the commit this page was made from: the board is docs/assets/projects/terminal.kicad_pcb and its schematic docs/assets/projects/555.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Terminal design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
