We are developing standard size mt7915 mPCIe card, and will be launched next month.

Hello moore,
would you mind telling me, is the standard size mt7915 mPCIe card launched yet?
Moore wrote lanch is next month…after that i guess it takes some time before start selling (manufacturing enough parts)
Hi, is this the card you were talking about?
Yes, we can get sample next week and start the test, thanks.
i tested dbdc after reboot (anywhere it was stated it does not work and needs a poweroff, did not found the thread) on my r2 with this card (mt7615 standard size).
i can boot 5.10.0-main (see wlan0 only), enable dbdc
echo 1 > /sys/kernel/debug/ieee80211/phy0/mt76/dbdc
see now wlan0 and wlan1. now reboot (no poweroff) to same kernel, did same steps with same result
my 5.10-main is only modified to add the eeprom-file patch…
Edit: found article with reboot-problem with dbdc:
hm,is this card is 4x4:4 MU MIMO OFDMA ? how so that it is only 2401Mbps, is it combined speed of 2,4 and 5G? thnx can you please explain this: is it SU-MIMO or MU-MIMO? " MU-MIMO configurations of
- 4 users: 4*1ss
- 3 users: 2 1ss + 1 2ss or 3*1ss
- 2 users: 2 2ss or 1 1ss + 1 2ss or 2 1ss"
i " * 4T4R with support of up to 2401Mbps PHY rate
- Configurable 4×4/3×3 or 2x2n+2x2ax DBDC"
Yes, it is mt7915a dualband selectable MU-MIMO card which can work at 4x4 2.4G (1200Mbps) or 4x4 5G(2400Mbps). If you use R64 with one 7915 card, it can become ax3200 router because 7622 has builtin 2.4G 4x4n (800Mbps) + 5G 4x4ax 2400Mbps=3200Mbps.

For dualband concurrent mode, mt7915d can be configured as 2x2 5G(1200) + 2x2 2.4G(600). It means we can have ax1800 concurrent router by only use 1 pcie slot.
AsiaRF has plan to have such card in the future. (chip is mt7915d with different pcb board)
I received my card with a metal shield. I was planning on adding radiators to the 2 chips on the board.
Is the shield for cooling purposes or it helps with interference?
It can reduce interference and it is ok to add heatsink on it, thanks.
What about antennas for the wifi chip?

It is only 2T2R, the other MT7915 card is 4T4R… I almost ordered 2 but then I saw it. Hmmmmz
1800Mbps with DBDC vs 2400Mbps without DBDC
This card is with 4T4R RF outputs in circuit too. Due to 2.4GHz and 5GHz can be combined in one RF outpupt. So 1x2.4GHz and 1x5GHz are combined to 1x(dual bands). Total are 2x(dual bands) outputs. Thanks for your asking!
Just got one - going to test it.
