Anyone could find the data sheet of 2088AB led matrix ? Or way to find it ?
Thanks alot. XD
Buzz it out, will not be hard.
+5 to 220 resistor as 1 lead, Gnd as 2nd lead.
Connect + to a pin, touch gnd to all other pins, see if you can find 8 that light up.
When you do, that + will be a common anode.
If a grounded pin does not light up, that pin is also an anode.
More than likely it will be similar to this:
