Questions
How big is the Thunderbolt pcie adapter PCB?
It measures 70 × 50 mm and has 6 copper layers, 1.56 mm thick.
What parts does the Thunderbolt pcie adapter use?
272 parts, built around the LT8350RV#PBF, MP2386GG-P, MX25L8006EM1I-12G and MX25L8006EM2I-12G. 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 Thunderbolt pcie adapter KiCad files?
From the antmicro/thunderbolt-pcie-adapter repository on GitHub, at the commit this page was made from: the board is thunderbolt-pcie-adapter.kicad_pcb and its schematic connectors.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Thunderbolt pcie adapter design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
