Questions
How big is the Preamp PCB?
It measures 30 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Preamp use?
10 parts, built around the OPA124P. 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 Preamp KiCad files?
From the cubitel/afm repository on GitHub, at the commit this page was made from: the board is hardware/preamp/preamp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Preamp design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
