Questions
How big is the KleverLogger PCB?
It measures 50 × 50 mm and has 4 copper layers, 1.6 mm thick.
What parts does the KleverLogger use?
75 parts, built around the ESP32-C3-WROOM-02-H4, MAX485ED, TJA1051T/3/1 and RS485. 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 KleverLogger KiCad files?
From the charclo/KleverLogger repository on GitHub, at the commit this page was made from: the board is KleverLogger.kicad_pcb and its schematic KleverLogger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KleverLogger design in my own project?
Its repository states no licence, so its author keeps all rights: ask charclo before reusing the design.
