PB16-2-PI

This is an adapter to use a Raspberry Pi W with the PB16 Cape instead of a PocketBeagle. This only supports the 16 local ports and the serial ports. The Expansion header does not work. Open source applications were used to create this PCB. KiCad was used for the PCB design, and LibreOffice for the documentation.

To order your own PCB upload the gerber.zip file to your favorite PCB manufacture of choice, I personally use jlcpcb.com.

Questions

How big is the Pi Zero 24 Diff PCB?

It measures 100 × 90.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Pi Zero 24 Diff use?

62 parts, built around the AM26C31IDRE4, 24LC256T-I/SN, CRGCQ0603F120R and RC0603JR-074K7L. 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 Zero 24 Diff KiCad files?

From the computergeek1507/PB_16 repository on GitHub, at the commit this page was made from: the board is Pi_Zero_24_Diff_SMD/Pi_Zero_24_Diff.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Pi Zero 24 Diff design in my own project?

Its repository states no licence, so its author keeps all rights: ask computergeek1507 before reusing the design.
