For those of us who are maybe a little tired of rainbows, we now have 'smart LEDs' in monochrome! Make your own smart Warm White LED arrangement with the same integrated LED driver that is used in our new fancy DotStar strips. Unlit, the color resembles an egg yolk.
Data input for the SK9822/DotStar LED package. Datasheet pin table lists pin 1 SDI as control signal input data.
Clock input for the SK9822/DotStar LED package. Datasheet pin table lists pin 2 CKI as control signal input clock data.
Signal and power-supply ground. Datasheet pin table lists pin 3 GND.
5 V power supply pin for the LED package. Datasheet pin table lists pin 4 VCC as power supply pin and the description states 5V application.
Clock output for cascading to the next LED. Datasheet pin table lists pin 5 CKO as control signal output clock data.
Data output for cascading to the next LED. Datasheet pin table lists pin 6 SDO as control signal output data.
