Questions

How big is the Nic2 PCB?

It measures 70.8 × 66.5 mm and has 4 copper layers, 1.59 mm thick.

What parts does the Nic2 use?

53 parts, built around the KSZ8463FRLI, TPD4S010DQAR, C0402C105K9PAC7800 and CRG0402F10K. 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 Nic2 KiCad files?

From the oxidecomputer/hw-gimletlet-nic repository on GitHub, at the commit this page was made from: the board is nic2.kicad_pcb and its schematic nic2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Nic2 design in my own project?

Its repository publishes it under the MPL-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).
