Questions
How big is the Pico buck board PCB?
It measures 89.4 × 88.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pico buck board use?
72 parts, built around the KST5551MTF. 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 Pico buck board KiCad files?
From the antonloof/pico_buck repository on GitHub, at the commit this page was made from: the board is pico_buck_board/pico_buck_board.kicad_pcb and its schematic pico_buck_board/pico_buck_board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pico buck board design in my own project?
Its repository states no licence, so its author keeps all rights: ask antonloof before reusing the design.
