Questions
How big is the OpenScent PCB?
It measures 60 × 35 mm and has 4 copper layers, 1.6 mm thick.
What parts does the OpenScent use?
61 parts, built around the ESP32-PICO-D4, CH343P, AMS1117 and MCP73831T-2ATI/OT-HXY. 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 OpenScent KiCad files?
From the anxndsgn/OpenScent repository on GitHub, at the commit this page was made from: the board is kicad file/OpenScent/OpenScent.kicad_pcb and its schematic kicad file/OpenScent/OpenScent.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the OpenScent design in my own project?
Its repository states no licence, so its author keeps all rights: ask anxndsgn before reusing the design.
