Adafruit Flora RGB Smart Neo Pixel v2 - 4pk
What's a wearable project without LEDs?
These daisy chain-able RGB LED pixels were designed specifically with wearables in mind! Each LED has a constant current driver and controller built right in, giving you 24-bit color with PWM brightness control. Each pixel only requires 3 connections; positive, negative, and i2c. An Flora can drive up to 500 of these at 30FPS before running out of RAM.
Each order comes with 4 individually controllable pixels. They are the high speed, 800khz version and are not compatible with the V1 400khz version.
