AsiaRF Wi-Fi module Adapter M2A2MP - M.2 A E Key to Mini PCIe

[Lorem_amicus (Michael Fischer)]

Hello,

I created this topic to discuss and share the possibilities of this AsiaRF M.2 to PCIe Adapter:

M.2 AE Key to Mini PCIe Wi-Fi module Adapter M2A2MP

The main goal is to determine whether the two PCI-E slots of the R4 are compatible with this adapter and a potential M.2 Wi-Fi card, specifically the AsiaRF AW7991-AE2.

For reference on direct compatibility, here’s a relevant forum discussion:

AsiaRF Wifi 7 module AW7991-AE2 - BE5000 NIC

It looks like there is something on AsiaRF which will be match to the category payable? [grafik] [grafik] I know it is a bit sarcastic, but with that power consumption it looks like a real wifi 7 NIC : Power Consumption: 11.5W After I realized the new maximum power consumption of BPI-R4 … I was a bit shocked. Wifi 7 tastes wasteful But this is off topic … Is this may the right time to create the new cooling topic? Or should I wait one month …

The primary focus is on the pinout of this adapter board. AsiaRF sent me a link that I’d like to share:

I don’t have time to check it today, but I will continue with this investigation in the next few days.

First view looks not bad?

How many lanes does it have? Mpcie only has 1, but the R4 does have 2 on the connector.

So if you need to use 2 lanes, then the adapter needs to be BPI-R4 specific, because there is no standard for it.

And the 7991 module:
