Questions
How big is the Simple p4 PCB?
It measures 50 × 65.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Simple p4 use?
75 parts, built around the TLV62569DBV, W25Q128JVSIQ, AP7361C-33E and ESP32-P4. 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 Simple p4 KiCad files?
From the huming2207/simple-p4 repository on GitHub, at the commit this page was made from: the board is simple-p4.kicad_pcb and its schematic simple-p4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Simple p4 design in my own project?
Its repository states no licence, so its author keeps all rights: ask huming2207 before reusing the design.
