Questions
How big is the MeshNode PCB?
It measures 75.4 × 52.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MeshNode use?
30 parts, built around the MIC5219-3.3YM5 and IRLML6344. 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 MeshNode KiCad files?
From the Karethoth/MeshNode repository on GitHub, at the commit this page was made from: the board is MeshNode.kicad_pcb and its schematic MeshNode.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MeshNode 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).
