This is a shield/breakout for Arduino Nano v3 that makes it easy to control addressable RGB LEDs, such as WS2811, WS2812 (Adafruit NeoPixels), SK6812, etc. The Arduino Nano v3 is an excellent Arduino compatible development board based on the ATmega328P.

RGB LEDs, pipe, fittings, etc not included

I made this shield because I was hand-wiring this same layout on perma-proto boards, which was time-consuming and unprofessional looking.

No level shifter is required since the Arduino Nano v3 outputs the same 5 volt logic level that the LEDs require.

One digital output pin (D4) is run through a data line resistor, as recommended by Adafruit's NeoPixel Best Practices.

The large 5V trace and GND pour should be rated for up to 2 amps. That's enough for about 33 LEDs at max output (solid white, full brightness). For larger quantities, power should be connected directly to the LEDs, and/or brightness should be limited in software.
