README
README.mdFPGA HDMI Experimenting Board PCB Layout Files
Note that this project is still in progress. Most of the work on the schematic is finished, with the pcb layout being the priority right now.
This board is designed to be relatively cheap (compared to other FPGA options with HDMI), and be fairly small at 2x2in. To meet these requirements some corners were cut (like ESD protection on the HDMI), though it still should function well.
This is not intended to be a consumer device, but rather a development and experimenting platform for those interested in playing around with HDMI.
ENJOY!

Questions
How big is the Mini fpga PCB?
It measures 50.8 × 50.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mini fpga use?
130 parts, built around the AP7331-WG and IS43R86400D-6TL. 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 Mini fpga KiCad files?
From the emusan/FPGA_HDMI-pcb repository on GitHub, at the commit this page was made from: the board is mini_fpga.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini fpga design in my own project?
Its repository states no licence, so its author keeps all rights: ask emusan before reusing the design.
