Questions

How big is the 0000.0123 PCB?

It measures 110 × 70 mm and has 2 copper layers, 1.6 mm thick.

What parts does the 0000.0123 use?

96 parts, built around the TL072 and TPA3255DDV. 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 0000.0123 KiCad files?

From the CyberHooves/0000.0123 repository on GitHub, at the commit this page was made from: the board is 0000.0123.kicad_pcb and its schematic 0000.0123.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the 0000.0123 design in my own project?

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