Questions
How big is the B PSU 0x00 PCB?
It measures 72.5 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the B PSU 0x00 use?
78 parts, built around the ADP5070AREZ-R7, ADP7118AUJZ-2.5-R7, ADP7118AUJZ-3.3-R7 and ADP7118WAUJZ-5.0-R7. 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 B PSU 0x00 KiCad files?
From the EmilsSturitis/BPSU repository on GitHub, at the commit this page was made from: the board is Hardware/B_PSU_0x00.kicad_pcb and its schematic Hardware/B_PSU_0x00.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the B PSU 0x00 design in my own project?
Its repository states no licence, so its author keeps all rights: ask EmilsSturitis before reusing the design.
