Questions

How big is the Black scope PCB?

It measures 89 × 60.5 mm and has 4 copper layers, 1.69 mm thick.

What parts does the Black scope use?

95 parts, built around the STM32G473VET6, LMV358 and LMV324. 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 Black scope KiCad files?

From the jgpeiro/black_scope repository on GitHub, at the commit this page was made from: the board is hardware/black_scope/black_scope.kicad_pcb and its schematic hardware/black_scope/black_scope.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Black scope design in my own project?

Its repository states no licence, so its author keeps all rights: ask jgpeiro before reusing the design.
