How to use an 8x8 LED Matrix? I have a LED Matrix just like this one



but couldn't find the data sheet for it (1855AS)
I asked around in my country and one guy told me to try attaching one side to 5v and the other to GND. Some LEDs worked fine and others didn't light up at all. In the end one if not more got burned.

So I'm here asking if anyone can tell me a way to figure out how it works.
I would appreciate the help!
You could check from where you have bought it. Maybe they have datasheet.
I found one similar, but before you must check if everything is the same and then do testing with power. LuckyLight
