Questions
How big is the Split Rail Supply PCB?
It measures 38 × 33 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split Rail Supply use?
34 parts, built around the TPS564255DRL, 150060GS75000 and B2B-PH-K-S(LF)(SN). 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 Split Rail Supply KiCad files?
From the fl0m0/Split_Rail_Supply repository on GitHub, at the commit this page was made from: the board is pcb/Split_Rail_Supply/Split_Rail_Supply.kicad_pcb and its schematic pcb/Split_Rail_Supply/Split_Rail_Supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split Rail Supply design in my own project?
Its repository states no licence, so its author keeps all rights: ask fl0m0 before reusing the design.
