Questions
How big is the Elemrv flask loopback PCB?
It measures 40 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Elemrv flask loopback use?
34 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 Elemrv flask loopback KiCad files?
From the aesc-silicon/kicad-projects repository on GitHub, at the commit this page was made from: the board is elemrv-flask-loopback/elemrv-flask-loopback.kicad_pcb and its schematic elemrv-flask-carrierboard/clock_reset.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Elemrv flask loopback design in my own project?
Its repository states no licence, so its author keeps all rights: ask aesc-silicon before reusing the design.
