Want one?
All production files you need to build your own board can be found here.
Gerber files as well as files needed for 3d printing are provided. Please note that the case design that supports the acryl layin may not be SLN printable. Please print them either in resin or nylon. I've used JLCPCBs printing service (black resin) and it turned out very good, so maybe take a look at that option.
Parts needed beside the MCU board and pcbs:
-
a 20pin 0.5mm pitch FCC/FCP Connector
-
48 mx hotswap sockets
-
48 1N4148 diodes in SOT-123 package
-
48 of your favourite switches

Questions
How big is the Frogger PCB?
It measures 228.6 × 80.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Frogger use?
106 parts. 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 Frogger KiCad files?
From the weteor/Froggr repository on GitHub, at the commit this page was made from: the board is pcb/frogger.kicad_pcb and its schematic pcb/frogger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Frogger design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
