Questions
How big is the Picard PCB?
It measures 81.5 × 50 mm and has 6 copper layers, 1.16 mm thick.
What parts does the Picard use?
166 parts, built around the STM32G071CBU3, TPS82130SILR, FUSB340TMX and TPS62180YZF. 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 Picard KiCad files?
From the weiiwang01/picard repository on GitHub, at the commit this page was made from: the board is PiCard.kicad_pcb and its schematic MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Picard design in my own project?
Its repository states no licence, so its author keeps all rights: ask weiiwang01 before reusing the design.
