Questions
How big is the Nerdqaxe+ PCB?
It measures 89 × 152 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Nerdqaxe+ use?
206 parts, built around the CSD95472Q5MC, TMP1075D, TXU0304PW and PMEG4030EP,115-JSM. 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 Nerdqaxe+ KiCad files?
From the shufps/qaxe repository on GitHub, at the commit this page was made from: the board is nerdqaxe+/nerdqaxe+/nerdqaxe+.kicad_pcb and its schematic legacy/qaxe+/qaxe/bm1366.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nerdqaxe+ design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
