Questions
How big is the MiniFeedMaster PCB?
It measures 58.4 × 83.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MiniFeedMaster use?
141 parts, built around the STM32F105RXTX, TPS82140SIL, SN6505BDBV and USBLC6-2SC6. 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 MiniFeedMaster KiCad files?
From the SG-O/MiniFeedMaster repository on GitHub, at the commit this page was made from: the board is MiniFeedMaster.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MiniFeedMaster design in my own project?
Its repository publishes it under the CC-BY-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
