Max Outputs per Port - Impact from Refresh Rate

[mausman32]

Quick question to confirm I'm understanding the F16v3 spec sheet appropriately.

I'm running only the main board, no expansion.  It says that should drive 1,024 pixels per output.  However, below that it shows lower pixels for refresh rate.

I currently have my xlights shows at 25ms (40 fps), so does that mean based on that refresh rate, i can only run 680 pixels per output?  Or can I do the full 1,024?

Thanks,
Matt

You should stick to 680 pixels per output if you want to achieve 40fps on that controller.  You can go more than 680 pixels without changing xlights, but the frame rate will reduce by skipping frames.  In my experience no-one will notice.  I do exactly this on a couple of controllers because I am too lazy to split up some large props across multiple ports.

If I add an expansion board to the F16v3 and go to 32 outputs, do I need to cut the 680 pixels / output in half as well (to 340)?  Or can I have 32 outputs with 680 pixels (max) and keep a 25ms (40 fps) show?

I'm pushing the limits of pixels for my controller.  I've got about 10,000 pixels and at only 16 ports, it's a challenge to get my props in a single physical area to a port and hit around 600-650 pixels per output.

yes (or some other split etc 500/180 pixels).

The F16v3 supports (16 * 680) = 10880 pixels @ 40FPS, an expansion board just gives you more outputs to spread that around.
