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.

Questions
How big is the Pi CM4 16 PCB?
It measures 142.1 × 106 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pi CM4 16 use?
118 parts, built around the SN74HCT245NSR, 74LVC1G07, 24LC256T-I/SN and AM26C31IDRE4. 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 CM4 16 KiCad files?
From the computergeek1507/PB_16 repository on GitHub, at the commit this page was made from: the board is Pi_CM4_16_SMD/Pi_CM4_16.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi CM4 16 design in my own project?
Its repository states no licence, so its author keeps all rights: ask computergeek1507 before reusing the design.
