Questions
How big is the Mycelium pcb PCB?
It measures 245.6 × 85.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mycelium pcb use?
134 parts, built around the ATMEGA168A-AU, MCP602-I/P, OP07 and 74HC04D. 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 Mycelium pcb KiCad files?
From the microresearch/mycelium repository on GitHub, at the commit this page was made from: the board is mycelium_pcb/mycelium_pcb.kicad_pcb and its schematic small_mycelium/small_mycelium.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mycelium pcb design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
