Questions
How big is the Meth PCB?
It measures 94 × 85.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Meth use?
36 parts, built around the ENC28J60-H and LM1084IT-3.3/NOPB. 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 Meth KiCad files?
From the lkundrak/meth repository on GitHub, at the commit this page was made from: the board is meth.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Meth design in my own project?
Its repository states no licence, so its author keeps all rights: ask lkundrak before reusing the design.
