Questions
How big is the Navrh03 PCB?
It measures 134.6 × 90.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Navrh03 use?
88 parts, built around the ESP32-DEVKITC-32UE, PCA9685PW and AOD417. 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 Navrh03 KiCad files?
From the Ejdmmm/MP repository on GitHub, at the commit this page was made from: the board is navrhAktualni/navrh03.kicad_pcb and its schematic MP/myPCB_01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Navrh03 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ejdmmm before reusing the design.
