On the apa 105 they will change they promised me … But with a one day … About 104 , they where always cheaper as the produces them selves in Korea …
Where can one go to order from them directly? Their website is useless, so when it comes to led chipsets that I will support, I usually go by what I can find/order from http://aliexpress.com, since that is where most of the library users will be getting their leds from (the leds sold by adafruit, sparkfun, etc… in the US are all usually based on things that were already being sold there for a while).

Do you have any suggestions on how many APA102 strips you can drive in parallel with the Teensy 3.1?
You need data and clock as well - so typically “SPI” - is it right?
There’s almost no benefit to running apa102 in parallel. You can drive a single line at 24mbps via hardware SPI on the teensy3.1 - to do parallel output would require enough cpu overhead that you’d be running a bit bang of the parallel lines at just below 3mbps, giving you an aggregate of 24mbps. (No, the cpu cost is not in the bit banging).
24mbps? Wow!
Did you try, how many APA102 LEDs in chain you can drive on hardware SPI?
I have a panel with 784 leds on it.
Is it the 28x28 version from RayWu?
Great to hear. Do you think it is also possible to run 1024 LEDs on the same data line?
