PCIe 3.0 M.2 M-Key/B+M Key Adapter with FPC for Raspberry Pi 5

I designed and made an open source PCIe HAB (hardware attached at the bottom) for Raspberry Pi 5 in KiCad.

Even though similar boards are widely available for purchase nowadays, I have had issues with some causing interference with WiFi, lacking LED indicators, FPC cable blocking MicroSD card reader, etc. 

Since I am designing a whole system with enclosure, I needed more control over board dimensions and flex cable positioning and length.

The design was inspired and enabled by George Smart – M1GEO design who reversed engineering PCIe connections of Raspberry Pi 5 before official documentations were released:

I also designed the flex cable that goes with this board.
