Questions
How big is the Dram PCB?
It measures 101.6 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dram use?
35 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 Dram KiCad files?
From the FionaLin13/dram_pcb repository on GitHub, at the commit this page was made from: the board is dram/dram.kicad_pcb and its schematic dram/dram.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dram design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
