AsiaRF Wifi 7 module AW7990-NPD - BE3600 - Mini PCIe

Asia RF offers a new WiFI 7 board with AP mode:

The NIC ist based on

→ MT7990AN (looks unused)

→ MT7976CN (which is also part of BPI-BE14)

The 24.10 of openwrt is with basic support for wifi 7 (If I’m not wrong).

Next year, the support will be much better :slightly_smiling_face: I’m pretty sure it will be supported …

I was looking at the schematics of the R4 for both mini PCIe slots.

Did I see this correctly — that each PCIe slot can deliver a maximum of 3 A peak, but typically only 3.3 V @ 2 A?

That would mean:

  • 6.6 W standard
  • 9.9 W peak

So the AW7916 (Wi-Fi 6E) with its rated 8 W (average ~5 W) works — but just barely. :pinching_hand:

→ It’s officially recommended to have 3.3 V @ 3–3.5 A.


But what about the AW7990, which requires up to 11.5 W?

→ That could already exceed the limits of the slot…

Maybe it’s possible to use it only for 2.4 or 5 GHz, and not both simultaneously? :see_no_evil:

Afaik maximum on 3v3 is 8A for all (including sfp)

This sounds good.

I was not sure what the ‘3A (peak 3A)’ stands for… is it what the R4 could deliver or what the wire could withstand?

It would be good if these

were possible :slightly_smiling_face:

This schematic is driving me crazy …

There is an A + E key variant from AsiaRF: AW7990-AE1

The documentation looks identical to the AW7990-NPD.

The only thing I noticed is one additional IPEX port.

What I wasn’t able to understand:

→ It is just an iFEM module (now I do) :pensive:

→ There are no additional external amplifiers on the board:
