Questions
How big is the Power brd PCB?
It measures 73.5 × 80.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Power brd use?
58 parts, built around the TPS5430DDAR and XT60PW-M. 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 Power brd KiCad files?
From the Caleb646/Flapjack repository on GitHub, at the commit this page was made from: the board is Design/V2/power_brd/power_brd.kicad_pcb and its schematic Design/V1/fc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Power brd design in my own project?
Its repository states no licence, so its author keeps all rights: ask Caleb646 before reusing the design.
