Questions
How big is the SUM25 PCB?
It measures 60 × 135.8 mm and has 6 copper layers, 2.4 mm thick.
What parts does the SUM25 use?
7 parts, built around the IPL1-104-01-L-D-K. 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 SUM25 KiCad files?
From the Down2Derive/SLAC-SM-25 repository on GitHub, at the commit this page was made from: the board is V2A_1.0/SUM25.kicad_pcb and its schematic SUM25.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SUM25 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Down2Derive before reusing the design.
