■ PIN DESCRIPTION

Pin Name

Function

LED1-LEDn

RGB or WLED cathode connection pin

Chip enable pin. High level activates the chip. Connect the

pin to VCC if not used, do not leave this pin floating

VCC

Power Supply

GND

Analog ground. In BL8581, for good LED current match, it is

recommended that the two GND pins should be tied together by

external copper.
