Questions
How big is the LambdaBuffer PCB?
It measures 28.2 × 34 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LambdaBuffer use?
16 parts, built around the OPA548T. 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 LambdaBuffer KiCad files?
From the AlexSchmid22191/LambdaBufferPCB repository on GitHub, at the commit this page was made from: the board is LambdaBuffer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LambdaBuffer design in my own project?
Its repository states no licence, so its author keeps all rights: ask AlexSchmid22191 before reusing the design.
