Questions
How big is the Funcion C02 PCB?
It measures 69.8 × 68 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Funcion C02 use?
44 parts, built around the ESP32-S3-WROOM-1-N8, HS96L03W2C03, LDL1117S33R and SS12. 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 Funcion C02 KiCad files?
From the RiQ4/HP_AIRQ_Monitor repository on GitHub, at the commit this page was made from: the board is Funcion_C02_HP_V1/Funcion_C02.kicad_pcb and its schematic Funcion_C02_HP_V1/Funcion_C02.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Funcion C02 design in my own project?
Its repository states no licence, so its author keeps all rights: ask RiQ4 before reusing the design.
