Questions
How big is the Scope afe PCB?
It measures 58.5 × 18.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Scope afe use?
23 parts, built around the BAT54S. 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 Scope afe KiCad files?
From the zoomlogo/scope_afe repository on GitHub, at the commit this page was made from: the board is scope_afe.kicad_pcb and its schematic scope_afe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scope afe design in my own project?
Its repository publishes it under the CERN-OHL-W-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
