Questions
How big is the CombinedBoard PCB?
It measures 56 × 42.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CombinedBoard use?
47 parts, built around the ESP32-WROOM-32 and TC1262-3.3VDB. 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 CombinedBoard KiCad files?
From the NikeGolf36/Sensor_PCB repository on GitHub, at the commit this page was made from: the board is combinedBoard.kicad_pcb and its schematic DaughteredESP32.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CombinedBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask NikeGolf36 before reusing the design.
