Questions

How big is the Buffer PCB PCB?

It measures 45.9 × 52.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Buffer PCB use?

28 parts, built around the 74HC245D. 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 Buffer PCB KiCad files?

From the abzman/cypress-logic-analyser-buffer repository on GitHub, at the commit this page was made from: the board is buffer PCB/buffer PCB.kicad_pcb and its schematic buffer PCB/buffer PCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Buffer PCB design in my own project?

Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
