Which concentrator do I need for use in an industrial x86-64 PC?

Hi,
I have an industrial x86-64 PC with a mini PCIe slot. Which concentrator do I need please? RAK833 is discontinued, and the RAK2247 has a very long lead time, leaving either the 2287 or 5146.

Is documentation available for either of these when using them in a PC? Everything I’ve seen so far points towards the RPi or the WisGate Developer Base. Or are they not designed for my purpose?

Do I need the SPI or USB version, and why?

Many thanks :slight_smile:
James
