Questions
How big is the SmartPowerBoard PCB?
It measures 59.8 × 41.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the SmartPowerBoard use?
117 parts, built around the RP2040, TPS561201DDCR, TPS56C230RJER and W25Q32JVSSIQ. 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 SmartPowerBoard KiCad files?
From the murexrobotics/electrical repository on GitHub, at the commit this page was made from: the board is Smart Power Board/SmartPowerBoard.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the SmartPowerBoard design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
