Flexible Adafruit DotStar Matrix 8x32 - 256 RGB LED Pixels

Flexible Adafruit DotStar Matrix 8x32 - 256 RGB LED Pixels — Adafruit — 2736

256-pixel flexible DotStar (APA102) LED matrix, 8x32, on a bendable PCB. Controlled via 2-wire SPI (clock + data), allowing faster updates than single-wire NeoPixels. Can be curved around surfaces.

FLEXIBLE ADAFRUIT DOTS5VDIDGNDCIC
  • 5Vlabelled 5V on matrix/strip input end

    5 V power input for the DotStar matrix/strip; Adafruit says connect strip 5V to board 5V and add bulk capacitance between 5V and GND for longer runs.

    Type · PowerVoltage · 5V
  • GNDlabelled GND on matrix/strip input end

    Common ground; Adafruit says a ground connection is required between microcontroller and strip in addition to signal lines.

    Type · GroundVoltage · 0V
  • DIDlabelled D or DI at originating/in end

    DotStar data input; Adafruit says labels are usually D or DI and connect to SPI MOSI or a digital pin.

    Type · GPIO
  • CIClabelled C or CI at originating/in end

    DotStar clock input; Adafruit says labels are usually C or CI and connect to SPI SCK or a digital pin.
