Questions
How big is the NODE PCB?
It measures 93.4 × 87.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the NODE use?
138 parts, built around the ESP32-WROOM-32, MAX485ED, RA-02 and LM358. 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 NODE KiCad files?
From the maivananh111/NODE_PCB repository on GitHub, at the commit this page was made from: the board is NODE.kicad_pcb and its schematic NODE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the NODE design in my own project?
Its repository states no licence, so its author keeps all rights: ask maivananh111 before reusing the design.
