Questions
How big is the MeshZero PCB?
It measures 65 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MeshZero use?
22 parts, built around the E22-900M33S and MPM3620AGQV. 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 MeshZero KiCad files?
From the MatthewIsHere/MeshZero repository on GitHub, at the commit this page was made from: the board is MeshZero.kicad_pcb and its schematic MeshZero.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MeshZero design in my own project?
Its repository states no licence, so its author keeps all rights: ask MatthewIsHere before reusing the design.
