Flexible Adafruit DotStar Matrix 8x32 - 256 RGB LED Pixels
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.
Pinout
- 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 - DI / Dlabelled 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 · digital input - CI / Clabelled 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.
