Questions
How big is the FPGA PCB?
It measures 50 × 50 mm and has 8 copper layers, 1.6 mm thick.
What parts does the FPGA use?
83 parts, built around the MAX20029ATIF/V+T and ECS-2520MV-160-CN-TR. 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 FPGA KiCad files?
From the WolframDioxide2/FPGA_devboard_poc repository on GitHub, at the commit this page was made from: the board is FPGA.kicad_pcb and its schematic Configuration.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the FPGA design in my own project?
Its repository states no licence, so its author keeps all rights: ask WolframDioxide2 before reusing the design.
