Questions
How big is the Powerboard PCB?
It measures 81.2 × 50.7 mm and has 4 copper layers, 1.61 mm thick.
What parts does the Powerboard use?
72 parts, built around the RP2040 and W25Q128JVSIM. 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 Powerboard KiCad files?
From the jacobmealey/capstone repository on GitHub, at the commit this page was made from: the board is hardware/powerboard/powerboard.kicad_pcb and its schematic hardware/developmentboard/developmentboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Powerboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask jacobmealey before reusing the design.
