10x M2x8 Nylon Hexagonal Splitter

Blink any color you need! Use the Tri-Color LED board as a simple indicator, or by pressing the red, green and blue channels, you can create any color. Very bright output.
This is a common anode design: to turn on a channel, you simply need to ground one of the R / G / B pins to illuminate that channel.
Lilypad is a wearable E-textile technology developed to have large connection pads to attach to clothing. Lilypad Tri-Color LED RGB features:
- Operating voltage: 3 - 5 VDC
- Design of common anode
- Density of the PCB: 0.8 mm
- Outside diameter: 20 mm
