Here’s the same (or very similar) item on Adafruit: http://www.adafruit.com/product/420

Short answer: not really.

Better answer: see “SmartMatrix”, which is totally FastLED-friendly. http://docs.pixelmatix.com/SmartMatrix/

It depends - if it is compatible with the stuff from here - http://docs.pixelmatix.com/SmartMatrix/ then you may be able to use the smart matrix object with it - but only on a Teensy 3.0/3.1 - and I’m not sure you can do multiple.

The input pins in the picture look the same, but the listing says it’s 1/4 scan. The SmartMatrix Library and shield supports driving 16x32 displays with 1/8 scan, and 32x32 displays with 1/16 scan. By the time you add shipping to the US, you’re probably better off ordering from Adafruit or Sparkfun. There’s a list of compatible displays in the Pixelmatix link Mark provided above.
