Questions
How big is the ThePreamp Controller PCB?
It measures 336 × 44.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ThePreamp Controller use?
32 parts, built around the APC-817B1-SL, CAT24C64WI-GT3 and TSOP34838. 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 ThePreamp Controller KiCad files?
From the Gninnorg/ThePreamp repository on GitHub, at the commit this page was made from: the board is Hardware/Controller/ThePreamp-Controller.kicad_pcb and its schematic Hardware/Analogue/Buffer-Opamp/Buffer-Opamp.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ThePreamp Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gninnorg before reusing the design.
