This is a shield/breakout for Adafruit Pro Trinket - 5V that makes it easy to control addressable RGB LEDs, such as WS2811, WS2812 (Adafruit NeoPixels), SK6812, etc. The Adafruit Pro Trinket - 5V is an excellent Arduino compatible development board based on the ATmega328.

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 Trinket Pro 5V 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.
