Questions
How big is the Ray2 PCB?
It measures 18.5 × 33.3 mm and has 2 copper layers, 1.04 mm thick.
What parts does the Ray2 use?
38 parts, built around the ESP32-C3 and AP2210N-3.3TRG1. 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 Ray2 KiCad files?
From the ohaut/ray2 repository on GitHub, at the commit this page was made from: the board is hardware/ray2.kicad_pcb and its schematic hardware/ray2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ray2 design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
