Questions
How big is the CASE PCB?
It measures 50.8 × 101.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CASE use?
57 parts, built around the ESP32-S3-WROOM-1U-N4, BMP581, BMI323 and ECMF02-2AMX6. 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 CASE KiCad files?
From the awetzelkern/CASE repository on GitHub, at the commit this page was made from: the board is CASE-Hardware/CASE.kicad_pcb and its schematic CASE-Hardware/CASE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CASE design in my own project?
Its repository states no licence, so its author keeps all rights: ask awetzelkern before reusing the design.
