GND
Ground connection for the DotStar LED bar power and signal reference. Adafruit DotStar guide identifies ground/GND as one of the four labelled strip connections.
Type · Ground
5V
5 V DC power input for the LED bar. Product page states the bar has GND and 5V wires and operating voltage DC5V; DotStar guide identifies 5V as the strip power pin.
Type · PowerVoltage · 5V DC; product page recommends keeping power under 15W / 3A at 5V for this bar.
DDI
DotStar data input at the originating end of the bar. Adafruit DotStar guide says the data line is usually labelled D or DI and connects to the microcontroller data pin.
Type · Signal
CCI
DotStar clock input at the originating end of the bar. Adafruit DotStar guide says the clock line is usually labelled C or CI and connects to the microcontroller clock pin.
