About the Raspberry Pi 5 PCIe Breakout

Raspberry Pi 5 PCIe Breakout is an open source PCB design by m1geo, published on GitHub under the MIT license. It is a 4-layer board measuring 50 × 50 mm, with 45 components from 17 distinct parts.

Other key parts include the Mini360. By type, the board carries 20 capacitors, 15 resistors, 5 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.
