Hi peeps,

I'm planning to make an installation that makes use of a bunch of (preferably daisy-chained) LED matrixes like this Adafruit one; https://www.adafruit.com/product/2278
Before I buy anything I'd like to make sure I understand correctly that these matrixes require about 3200 bytes of RAM to be able to PWM the whole thing fast enough. A Teensy 3.6 has 256kByte of RAM so the daisy chaining of about 10 of these boards shouldn't be much of an issue for it?

I'd like to use one of these smartMatrix shields to connect the thing, so the thing can be hidden away nice and clean. https://www.adafruit.com/product/1902

Then at last; I was actually looking at aliExpress to see what options are there. Does anyone have any recommendations there, or any things I should look out for?
The thing seems to be the exact same thing; -Downsized link-

Hope you can help me out! Thanks in advance
