Questions

How big is the Differential SPI Adapter PCB?

It measures 89.8 × 21.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Differential SPI Adapter use?

23 parts, built around the THVD1450D, AM26LV31CD and AM26LV32CD. 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 Differential SPI Adapter KiCad files?

From the koki0517/Differential-SPI-Adapter repository on GitHub, at the commit this page was made from: the board is Differential-SPI-Adapter.kicad_pcb and its schematic Differential-SPI-Adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Differential SPI Adapter design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
