LED Matrix chain

Newbie question
I need to know what additionally I will need to chain LED matrixes.

Using a RGB LED Matrix Panel – 32x32 and following the instructions
do I need a one “Adafruit RGB Matrix HAT + RTC for Raspberry Pi - Mini Kit” to run 9 Matrixs or one per multiple Matrixs?

Also the ones being sold here are different from the adafruit model

even though it describes it as being adafruit in the info!
Will it technically work the same in every way apart from size?

thanks a lot
