Questions
How big is the IsItOpen PCB?
It measures 100 × 99 mm and has 2 copper layers, 1.6 mm thick.
What parts does the IsItOpen use?
62 parts, built around the ESP32-DEVKITC-VE, LM4562NA, LM4871 and MCP4801-E/P. 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 IsItOpen KiCad files?
From the UnHolds/FsInf-Control repository on GitHub, at the commit this page was made from: the board is PCB/IsItOpen.kicad_pcb and its schematic PCB/IsItOpen.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the IsItOpen design in my own project?
Its repository states no licence, so its author keeps all rights: ask UnHolds before reusing the design.
