Questions
How big is the Envelope PCB?
It measures 39.5 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Envelope use?
81 parts, built around the ATMEGA328PB-AU, TL072 and L7805. 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 Envelope KiCad files?
From the marangisto/Envelope repository on GitHub, at the commit this page was made from: the board is Envelope.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Envelope 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).
