Questions
How big is the KinetiCoreDC PCB?
It measures 40 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the KinetiCoreDC use?
183 parts, built around the STM32G070CBT6, 74LVC2G126DC, THVD1400D and NSI45020A. 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 KinetiCoreDC KiCad files?
From the axpaul/KinetiCoreDC repository on GitHub, at the commit this page was made from: the board is KinetiCoreDC.kicad_pcb and its schematic Connector.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the KinetiCoreDC design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
