Questions
How big is the Mixers PCB?
It measures 90 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mixers use?
133 parts, built around the LM358, LM386, BF998R 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 Mixers KiCad files?
From the k1zmt/SSB85MultiPCB repository on GitHub, at the commit this page was made from: the board is Mixers/Mixers.kicad_pcb and its schematic AD831HotBoard/AD831HotBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mixers design in my own project?
Its repository states no licence, so its author keeps all rights: ask k1zmt before reusing the design.
