Questions

How big is the MESH PCB?

It measures 56.5 × 28.2 mm and has 2 copper layers, 1.6 mm thick.

What parts does the MESH use?

71 parts, built around the CC1101RTKR, TP4056 and AO3401A. 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 MESH KiCad files?

From the vlad-mod/DSAN repository on GitHub, at the commit this page was made from: the board is MESH-pcb/MESH.kicad_pcb and its schematic MESH-pcb/MESH.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the MESH design in my own project?

Its repository states no licence, so its author keeps all rights: ask vlad-mod before reusing the design.
