Questions
How big is the RAM Module PCB?
It measures 41.5 × 41.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the RAM Module use?
22 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 RAM Module KiCad files?
From the ahmadexp/Open-Source-PC110 repository on GitHub, at the commit this page was made from: the board is PCB/RAM-16MB/RAM-Module.kicad_pcb and its schematic Mods/CPU Upgrade/bgacpu-dualcon/bgacpu-dualcon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RAM Module design in my own project?
Its repository states no licence, so its author keeps all rights: ask ahmadexp before reusing the design.
