Questions
How big is the 6g att PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 6g att use?
150 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 6g att KiCad files?
From the zxkmm/attenuator repository on GitHub, at the commit this page was made from: the board is 6g_att/6g_att/6g_att.kicad_pcb and its schematic 6g_att/6g_att.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 6g att design in my own project?
Its repository publishes it under the AGPL-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).
