Questions
How big is the Gb fpga PCB?
It measures 80.1 × 78.6 mm and has 4 copper layers, 1.2 mm thick.
What parts does the Gb fpga use?
151 parts, built around the TLV61046ADBV, TXS0108EPW, FT2232HQ and MBT3904DW1. 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 Gb fpga KiCad files?
From the blazer82/gb.fpga repository on GitHub, at the commit this page was made from: the board is hardware/cpu-board/kicad/gb-fpga.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gb fpga design in my own project?
Its repository states no licence, so its author keeps all rights: ask blazer82 before reusing the design.
