Questions
How big is the Node PCB?
It measures 41 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Node use?
14 parts, built around the MAX485ED, L7805CV and RJ45. 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 aetas/MqGateway-PCB repository on GitHub, at the commit this page was made from: the board is Node/Node.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Node design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
