About the Raspberry Pi 5 M.2 Hat
Raspberry Pi 5 M.2 Hat is an open source PCB design by m1geo, published on GitHub under the MIT license. It is a 4-layer board measuring 65 × 56 mm, with 40 components from 17 distinct parts.
Other key parts include the Mini360. By type, the board carries 19 capacitors, 11 resistors, 4 diodes, 3 connectors, 1 IC and 1 transistor.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
A crude reverse engineering of the Pi5 PCIe connector & potential breakout boards.

In this bare-bones project I document a working PCIe pinout talk through my hardware tinkering to get the Raspberry Pi 5's PCIe connected to something. I had only seen Raspberry Pi's boards with their RP2040 and lots of parts on board. My professional experience with PCIe was that it either just goes or it really doesn't. I decided to try and make it do something for no reason other than the technical challenge.
