Questions
How big is the PowerBoardToid PCB?
It measures 58.7 × 31 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PowerBoardToid use?
31 parts, built around the TPS56528DDA, TPS62162DSG, TPS62163DSG and SMAJ18CA. 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 PowerBoardToid KiCad files?
From the codujla/PowerBoard repository on GitHub, at the commit this page was made from: the board is hardware/PowerBoardToid.kicad_pcb and its schematic hardware/PowerBoardToid.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PowerBoardToid design in my own project?
Its repository states no licence, so its author keeps all rights: ask codujla before reusing the design.
