This led matrix is arranged in an 8×8 configuration with 12.5mm spacing between the centers of the 64 leds. T
he matrix is sized to be 10cm x 10cm with mounting holes along the edge and middle of the pcb.
The 64 leds can consume 3.84A @5V for a total 19.2Watts of power.
Cables are already soldered. This is a plug-and-play setup.
In one of our installations we successfully run 15 modules (960 leds) at 3.7V with 3.3V signallevel.
