Questions
How big is the SIC431 PCB?
It measures 127 × 127 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SIC431 use?
95 parts. 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 SIC431 KiCad files?
From the IllinoisRoboticsInSpace/IRIS_PCB repository on GitHub, at the commit this page was made from: the board is boards/Power Distribution Board Ver.1/SIC431.kicad_pcb and its schematic boards/12V_Power_System/12V_Power_System.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SIC431 design in my own project?
Its repository states no licence, so its author keeps all rights: ask IllinoisRoboticsInSpace before reusing the design.
