Questions
How big is the VayuO2 PCB?
It measures 136 × 88 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VayuO2 use?
180 parts, built around the B2405S-2WR2, CP2102N-A01-GQFN28R, ESP32-WROOM-32UC and PS2801-1. 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 VayuO2 KiCad files?
From the wyolum/vayuO2 repository on GitHub, at the commit this page was made from: the board is PCB_layout_v1/vayuO2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the VayuO2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask wyolum before reusing the design.
