From the project

The Raspberry Pi Hat

A Raspberry Pi 4 add-on board to protect and power the Pi from the v4 SR kit, and provide a visual indicator of the state of the brain board's software as detailed in the specification.

The BOM and assembly files can be generated with KiCAD JLCPCB tools and the JLCPCB part codes are already assigned.
