3x3 mimo and miniPCIe cards, building HP backhaul

Some are selling these cards and claim they work with routerboards.
Some cards do need 5V power supply and there are only 2 or 3 routerboards that have miniPCIe slots.

Anybody has workarounds or solutions?

I am really looking to set up a high capacity link with MT and 3x3. But the rb800 seems to be a little over the budget and has no 5V pins (only 3V and board voltage). To get 5V from the usb or serial needs soldering and that is the last I want to do on an expensive board like the rb800. Disaster waiting to happen! :?

So, anybody with any experiances?
What cards?
What link caracteristics? (Distance, fresnell, urban or open space etc.)
What antenna's used?

I was thinking of using Duo polorised dish antenna's combined with one mesh that I than can mount close to the dish but under an 45 degree angle. The cross-chain channel separation would be probably better this way than a triple polorized all-in-one antenna? Anybody been playing with something like this?

Hola Rudy!


I think JP4 is 5.5Volts in RB800.

Fan Connectors
You can connect up to four fans to the RouterBOARD, but only one pair of them will work at a time. They will
receive either 3.3V or 5.5V DC power. The board supports fan speed feedback signaling. RouterOS can be
configured to change the active fan, if the current active one is not rotating (note that if a fan does not have
rotation sensor, it will be considered failed).
JP1 and JP3 are 3.3V connectors, only one of them will power a cooling fan at the same time, other one will
be started when the first stops.
JP2 and JP4 are 5.5V connectors, only one of them will power a cooling fan at the same time, other one will
be started when the first stops.
To enable rotation of two fans simultaneously, simply connect one 3.3V fan to JP1 and a 5.5V fan to JP4
(outside of the pair).

Hi Martín!

Well, I must have misread somewhere becuase you're right. All the info about rb800 talks about 5.5V so I haven't got a clue why I had the impression this was different? Thanks for the correction. :)
