Circuit Diagram

This provides a visual reference for wiring of the components. They aren't true to scale, just meant to be used as reference. The 144 LED/m high density strip does not have labels for serial clock and data signals, so you'll need to use the power and ground labels to reference the correct pins.

In my build, I wired up 2 separate LED strips (Data Not Chained). I decided to leave this out in the circuit diagram for clarity purposes.  The second LED strip share the SCK and MO pins, however the power and ground have their own pins.

Wired Connections

The DotStar strip has labels noting the power and ground pads as well as an arrow for depicting the flow of the data. The 2200mAh battery plugs directly into the Adafruit Feather.

  • 3V from Feather to +Power on DotStar Strip
  • MO from Feather to Data Input (DI) on DotStar Strip
  • SCK from Feather to Clock Input (CI) on DotStar Strip
  • EN and GND on Feather to Switch
