Questions
How big is the Kria k26-devboard PCB?
It measures 118 × 100 mm and has 8 copper layers, 1.52 mm thick.
What parts does the Kria k26-devboard use?
660 parts, built around the 74AVC4T245RSVRG4, RT6236AHGQUF, TPD4E05U06QDQARQ1 and LTC4358CDE#PBF. 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 Kria k26-devboard KiCad files?
From the antmicro/kria-k26-devboard repository on GitHub, at the commit this page was made from: the board is kria-k26-devboard.kicad_pcb and its schematic PoE.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kria k26-devboard 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).
