Questions
How big is the Ckt defect PCB?
It measures 99.1 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ckt defect use?
97 parts, built around the ESP32-S2-SOLO-N8, AP63205WU, MAX98357AETE+T and TMP1075D. 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 Ckt defect KiCad files?
From the IowaScaledEngineering/ckt-defect repository on GitHub, at the commit this page was made from: the board is kicad/ckt-defect/ckt-defect.kicad_pcb and its schematic kicad/ckt-defect/ckt-defect.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ckt defect design in my own project?
Its repository states no licence, so its author keeps all rights: ask IowaScaledEngineering before reusing the design.
