Just got this delivered from AliExpress, I may be new to MCU and wiring and such but I know this isnt ACTUALLY asking me for 2 ground wire connections? Seems shady or am I just overthinking it.
#4x4 LED Matrix double ground?

I would be massively surpised if they were not connected together, if you have a multimeter then you could just do a continuity test.
its just likely got a ground on both sides so you have a choice and if you have them orientated differently.
although it is possible that its isolated so you can use different voltage reference on your data line vs power line. however i think its unlikly. as mentioned above. run a continuity test and see if they are connected together or not.

yeah if your working on stuff like this then having a decent multimeter is a must.
