NeoPixel RGB LED with Integrated Driver (10-pack)

Overview

The Adafruit 1655 is a pack of 10 addressable RGB LEDs in a standard 5050 package with an integrated driver chip. Each LED uses a single-wire control protocol that allows multiple units to be chained together to create complex lighting effects. This specific variant features the 4-pin design for easier PCB routing and simplified wiring compared to older 6-pin versions.

Why Choose This Part

By integrating the driver chip and the LED into a single 5050 package, this component significantly reduces the bill of materials and board space required for RGB control. The 18mA constant current drive per channel ensures consistent color and brightness across long chains even if the supply voltage fluctuates slightly.

Applications

Getting Started

These LEDs are most commonly controlled using the Adafruit NeoPixel library or the FastLED library for Arduino and CircuitPython. Connect a 5V power supply and a single digital output pin from your microcontroller to the Data Input (DI) pin of the first LED. It is recommended to place a 100nF decoupling capacitor across the power pins of each LED to minimize switching noise.
