[SOLVED] VIA EPIA P910 PCIe Expansion Slot?

[Genralkidd]

I have a VIA EPIA P910 Pico ITX board that I want to start using again soon and it's always had a "high speed extension slot" on the side of it that supports PCIe. However I cannot find any information at all about that expansion slot as well as any adapters for it.

EPIA-P910 (EOL)

The VIA EPIA-P910 provide a versatile platform for building a diverse range of ultra-small form factor embedded and IoT devices.

Does anyone know exactly what that expansion slot really is? Is it proprietary and I'm SOL for finding PCIe adapters for it? Or is it actually an standard slot that goes by a different name and there are PCIe risers/adapters for it?

The board-to-board slot labeled as “CN3” is a combination connector reserved for connecting to a customized expansion card. The connector pinout supports PCIe, LAN, USB 2.0, Audio, SDIO and SIM.

I take it though that there's no connectors or adapters already on the market? I couldn't find any pre-existing accessories from VIA for that connector.
