MT7916 2x2 WiFi6 BW160 mPCIe card

[moore (moore liu)]

This card can make BPI-R:grinning:64/R3 to have AX3000 dualband/AX7800 tri-band support and we can find upstream driver after kernel 5.18.

Anyone have any experience using this card on BPI-R64?

I guess on r64 we will fall into the current limit again like for mt7619. I recently got such card can try if it is recognized on my r64.

For r3 i need adapter for ngff as minipcie slot is usb only

I read here V1.1 was upgraded:

[BPI-R64] Possible hardware improvements

Just as a FYI, on the R64 v1.1 board I bought last month the current limiting capacitors were already updated to 3K for a 3.3V/2.26A current limit (above the SY6280A recommended 2A maximum limit) versus the old 4K7 for a 3.3V/1.44A current limit. But that’s only for the 3.3V PCIe lines, not the extra 5V supplied to reserved lines 49 and 51 (and also dubiously to lines 46 WPAN and 48 +1.5V but which is generally unused) for use by BananaPi’s own wireless cards and some others such as the Unielec…

But I guess it is not enough, needs at least 3A. Guess only option for me is to bypass the current limiter. The main 3.3V supply has a current limiting function also.

Is there any chance this card gets fried by the extra 5V that is on the pcie connector?

Anyway it is available on backorder, so I guess it is out of stock.

On the 1.1 schematic i do not find the boosted power adjustment.
