Questions
How big is the Memdump hw PCB?
It measures 56.1 × 86.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Memdump hw use?
81 parts, built around the STM32F103C8T6, 74HC595, AMS1117-3.3 and SI4800BDY. 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 Memdump hw KiCad files?
From the Derisis13/memdump repository on GitHub, at the commit this page was made from: the board is memdump_hw.kicad_pcb and its schematic memdump_hw.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Memdump hw design in my own project?
Its repository states no licence, so its author keeps all rights: ask Derisis13 before reusing the design.
