Universal 5V-24V power input.
DC WS2811 LED smart pixel controller 2048pixels controlled with 76 kinds of patterns
The tester has a power input (red and black) and pixel output with G,D,+ wires.
These are Ground (0V), Data and +ve voltage.
The placement of the wires will indicate which colour should be used. Red is typically always +ve power.
The tester can be used for directly connecting up to about 100 pixels.
Once more than about 100 pixels are to be connected then fusing and power injection should be used.
