It looks like there is something on AsiaRF which will be match to the category payable?

I know it is a bit sarcastic, but with that power consumption it looks like a real wifi 7 NIC :see_no_evil: :

Power Consumption: 11.5W

After I realized the new maximum power consumption of BPI-R4 ā€¦ I was a bit shocked. Wifi 7 tastes wasteful :neutral_face: But this is off topic ā€¦

:thinking: Is this may the right time to create the new cooling topic? Or should I wait one month :wink: ?

So all we need is an adapter to convert the custom 2-lane mpcie of the BPI-R4 to the m.2 a+e 2 lanes. This adapter may also need a 12V ā†’ 3.3V buck converterā€¦

Who else could solve this problem like the great company asiarf:

M2A2MP-C01-1-mPCIe-to-M.2_Size
M2A2MP-C01-1-mPCIe-to-M.2_Size1000Ɨ1000 155 KB

ā†’ buck converter: I thought, turning off the 12V should be enough?

Iā€™m more concerned about MT7991A driver support (in combination with MT7976C).

I found on MediaTek - WikiDevi.Wi-Cat.RU some routers with this chip: ā†’ Xiaomi BE5000 and TP-LINK TL-7DR5160 ā€¦ .

ā†’ but it looks this models will not get support from openwrt.

ā†’ I did not no know much about the Linux driver side ā€¦

Does it support the second lane on the BPI-R4? It is not a standard pinout.

Okay,

I wrote an E-mail to AsiaRF:

I will post the answer.

They will probably tell you to buy their ap7988

We have luck, they anwered!

For the pinout of the adapter I created a own chat:

So there is the pinout that AsiaRF send me:

Hi, would you be so kind to explain me, why ti AsiaRF M.2 AE Key to Mini PCIe Wi-Fi module adapter so special? Isnā€™t enough just to buy one from aliexpress and stick the mini-pcie card to miniPC or this whole thread is for BPI-R4 ?

thnx so much,.

The pinout of a Mini PCIe card should be standardized. But in this special case you can see it just as a ā€œmechanical partā€.

So, you need to control the pinout of this card and the pinout of the R4 ā€¦ (the card has two lanes). Exectly for this there is the additional chat:

I did not have time jet.

(the card has two lanes).

i tink that this card:

has only one PCI-3.0 lane , do you have manufacturer datasheet/ proof for 2 lanes? btw: official M2A2MP should have only one line by standard:

. R4 has two of them available for wifi 7 modules.

12

You should have looked on site of the board:

We talked about this there:

The 2nd lane shoult be #17 #19 #45 #47

But ā€œthe problemā€ is not the second lane. Both R4 Mini PCI-E Sockets have 2 lanes. The problem is that the Adapter has an ā€œxā€ on this numbers :smiling_face_with_tear::

This is a good overview of the pinout:

14

Thnx for the hawkeye view:-)

Almost buy wrong oneā€¦ Now iā€™m interested only in this one:

because my minipc has only one lineā€¦

i suppose that this means it os only one lineā€¦

Platform

  • 32bit RISC-V MCU for Wi-Fi protocol and Wi-Fi offload
  • Embedded SRAM and ROM
  • PCIe3.0 interface

what about linux kernel support, do you know anything?

15

No, but it has good chances to get supported! :+1:

Iā€™m also interested in it! This is why I created this chat:

I will give you the answer there (will not mix the topics)
