Ultra High Density DotStar LED PCB Bar - 128 LEDs

OverviewPinoutWiringRelated groups
Ultra High Density DotStar LED PCB Bar - 128 LEDs — Adafruit — 3776

Look, just bolt this to your ceiling fan already - we know that's the first thing you thought of! OK, so you already know what DotStar LEDs are - those digitally controllable LEDs that have two data wires and higher refresh rates for than NeoPixels.

Pinout

  • 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.
  • D / DI

    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
  • C / CI

    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.
