Questions
How big is the CosSin PCB?
It measures 100 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CosSin use?
50 parts, built around the ATMEGA328P-PU, LM1876T and BC547. 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 CosSin KiCad files?
From the cybaer/CosSin repository on GitHub, at the commit this page was made from: the board is HW/CosSin.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the CosSin design in my own project?
Its repository states no licence, so its author keeps all rights: ask cybaer before reusing the design.
