Questions
How big is the Preamp PCB?
It measures 19.1 × 14.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Preamp use?
23 parts, built around the PHA-13LN and BAV99. 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 stockmann-lab/Open_Source_MRI_Tools_MGH repository on GitHub, at the commit this page was made from: the board is preamp/preamp_board/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 states no licence, so its author keeps all rights: ask stockmann-lab before reusing the design.
