Questions
How big is the TFLN AI NODE X2 SERVER CHASSIS IO PCB?
It measures 295 × 140 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TFLN AI NODE X2 SERVER CHASSIS IO use?
9,027 parts, built around the HMC8410LP2FE, ISL69260IRAZ-T, SI5395A-A-GM and GRM155R71C104KA88. 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 TFLN AI NODE X2 SERVER CHASSIS IO KiCad files?
From the Lightiam/tapeout_07 repository on GitHub, at the commit this page was made from: the board is 07_engineering_reconcile/00_OPEN_IN_KICAD_PATCHED/TFLN_AI_NODE_X2_SERVER_CHASSIS_IO.kicad_pcb and its schematic 07_engineering_reconcile/00_OPEN_IN_KICAD_PATCHED/TFLN_AI_NODE_X2_SERVER_CHASSIS_IO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TFLN AI NODE X2 SERVER CHASSIS IO design in my own project?
Its repository states no licence, so its author keeps all rights: ask Lightiam before reusing the design.
