Questions
How big is the Dev board PCB?
It measures 80 × 59.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dev board use?
39 parts, built around the AHT20-F, KT-0805G, KT-0805Y and NCD0805R1. 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 Dev board KiCad files?
From the ray33ee/radiator_rust repository on GitHub, at the commit this page was made from: the board is schematics/dev_board/dev_board.kicad_pcb and its schematic schematics/dev_board/dev_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dev board design in my own project?
Its repository states no licence, so its author keeps all rights: ask ray33ee before reusing the design.
