Questions
How big is the LamaKey fpga PCB?
It measures 121.3 × 123.8 mm and has 4 copper layers, 1.64 mm thick.
What parts does the LamaKey fpga use?
147 parts, built around the ICE40UP5K-SG48ITR50, W25Q64JVSSIQ, USBLC6-2SC6 and ESD7551N2T5G. 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 LamaKey fpga KiCad files?
From the Wagner-Sebastian/Lamakey repository on GitHub, at the commit this page was made from: the board is LamaKey-fpga/LamaKey-fpga.kicad_pcb and its schematic Keyscan.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LamaKey fpga design in my own project?
Its repository states no licence, so its author keeps all rights: ask Wagner-Sebastian before reusing the design.
