Questions
How big is the Kicadpartsplacer PCB?
It measures 181 × 87.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kicadpartsplacer use?
63 parts, built around the ESP32-WROOM-32, MAX485ED, AMS1117-3.3 and TB007-508-04BE. 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 Kicadpartsplacer KiCad files?
From the JandroGG/PCB_CPU_Data_logger_rs485 repository on GitHub, at the commit this page was made from: the board is Part Placer/kicadpartsplacer.kicad_pcb and its schematic CPU BOYA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kicadpartsplacer design in my own project?
Its repository states no licence, so its author keeps all rights: ask JandroGG before reusing the design.
