Questions
How big is the DRAM Tester PCB?
It measures 65 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DRAM Tester use?
11 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 Tester KiCad files?
From the cloudree/DRAM_Tester repository on GitHub, at the commit this page was made from: the board is DRAM_Tester/DRAM_Tester.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DRAM Tester design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
