Questions
How big is the Logix core PCB?
It measures 100 × 80 mm and has 6 copper layers, 1.6 mm thick.
What parts does the Logix core use?
238 parts, built around the FT230XQ-R, MP5470GL-0000-P, MT41K256M16TW-107:P and TPUSBLC6-4SC6. 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 Logix core KiCad files?
From the Gherkin/logix-core repository on GitHub, at the commit this page was made from: the board is logix-core.kicad_pcb and its schematic 7-segment.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Logix core design in my own project?
Its repository states no licence, so its author keeps all rights: ask Gherkin before reusing the design.
