Questions
How big is the Envelope v1 1 pcb a PCB?
It measures 80 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Envelope v1 1 pcb a use?
120 parts. 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 v1 1 pcb a KiCad files?
From the EchelonForce/envelope_generator_AS3310 repository on GitHub, at the commit this page was made from: the board is envelope_v1/envelope_v1_1_pcb_a.kicad_pcb and its schematic envelope_v1/envelope_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Envelope v1 1 pcb a design in my own project?
Its repository states no licence, so its author keeps all rights: ask EchelonForce before reusing the design.
