This can drive 1024 LEDs through 16 XLR connections. Inside is a 5v 40a PSU, two Fadecandy‘s and a slimline USB hub. This is a smaller version of the one I used to drive 1800 LEDs for the Embraer installation at Farnborough the other week. The box is a 20 hole stage box. Really pleased with this system now. At Farnborough it ran 24 hours a day for ten days without a problem.
