Have a Falcon F16v3 with one 4 port Differential Expansion board connected. Can I add a second 4 port Differential Expansion board? If so will the Meanwell 350 power supply be enough to handle the additional board?

Running 100 12v pixels on each of the F16v3 ports so 1600 pixels on the controller.

I do not think one meanwell power supply is enough for what you have now.

The 4 port Differential Expansion board draws minimal power from the F16v3, perhaps an amp or two, supplied via the ribbon cable.

A second board can be connected (set the jumpers correctly) BUT the second board will need its own power connection (but not a large supply) because the ribbon cable to that second board will not supply power, just data.

Camphouse, Correct me if you are not asking the following:


"Can I have two expansion boards getting their commands from a single F16V3?"



The answer to this is no.  There is only one serial connection that has all 4 connections in it.  If you use all 4 in the first board, the remaining serial outputs are just duplicates of the individual outputs that you are already using.


The best way to connect more than one receiver is to use the differential expansion sender.  It will give you 4 outputs for receivers (16 total outputs).  You can even put a 5th one on the main board's output, if you need it.  (It takes a bit of manipulation to get them all 5 to work, but it isn't bad or hard.)


As far as the power supply, it depends on a lot of factors. (Number of pixels, maximum intensity you are driving them at, length of cable between the power supply and the receiver, etc.) Usually when you have that many pixels, a second power supply may be in order.   Or better yet, power supplies at the receiver boards.
