Questions
How big is the Pizero hat PCB?
It measures 65 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pizero hat use?
22 parts, built around the MAX-M10S and RFM98W-433S2. 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 Pizero hat KiCad files?
From the MTalon63/HAB repository on GitHub, at the commit this page was made from: the board is electronics/pizero_hat/pizero_hat.kicad_pcb and its schematic electronics/pizero_hat/pizero_hat.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pizero hat design in my own project?
Its repository states no licence, so its author keeps all rights: ask MTalon63 before reusing the design.
