Questions
How big is the CertusNX PCB?
It measures 40 × 40 mm and has 4 copper layers, 1.59 mm thick.
What parts does the CertusNX use?
125 parts, built around the LFD2NX-17-7MG121I, TPSM53604RDA, TLV62569ADRL and W25Q128JVPIQ. 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 CertusNX KiCad files?
From the c4tsnest/certus_test repository on GitHub, at the commit this page was made from: the board is CertusNX.kicad_pcb and its schematic CertusNX.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CertusNX design in my own project?
Its repository states no licence, so its author keeps all rights: ask c4tsnest before reusing the design.
