Questions
How big is the Panel PCB?
It measures 225 × 140 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Panel use?
422 parts, built around the ADAU1467WBCPZ300, W25Q128JVSIQ, ADAU1962AWBSTZ and 1SMA5927A. 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 Panel KiCad files?
From the LeanderGlanda/Endstufe repository on GitHub, at the commit this page was made from: the board is Endstufe_v2/Panel/Panel.kicad_pcb and its schematic Endstufe_v1/Endstufe.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Panel design in my own project?
Its repository states no licence, so its author keeps all rights: ask LeanderGlanda before reusing the design.
