Questions
How big is the V25Panel PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the V25Panel use?
211 parts, built around the ATSAMD51J20A-AU, 74AHC1G125GW, AP2112K-3.3TRG1 and MCP73831T-2ACI/OT-HXY. 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 V25Panel KiCad files?
From the maholli/SAM32 repository on GitHub, at the commit this page was made from: the board is hardware/SAM32_v25/panel/v25Panel.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the V25Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask maholli before reusing the design.
