Questions

How big is the Pi HAT V2 PCB?

It measures 71.7 × 75.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pi HAT V2 use?

42 parts, built around the MP2315GJ-Z, BSS138 RFG and XT60PW-M. 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 Pi HAT V2 KiCad files?

From the danielwilczak101/EasyControls repository on GitHub, at the commit this page was made from: the board is ISAAC/PCB/Pi_HAT/V2/Pi_HAT_V2/Pi_HAT_V2.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pi HAT V2 design in my own project?

Its repository states no licence, so its author keeps all rights: ask danielwilczak101 before reusing the design.
