Adafruit NeoPixel Jewel - 7 x 5050 RGB LED

Adafruit NeoPixel Jewel - 7 x 5050 RGB LED

$5.90

Adafruit has fit seven tiny 5050 (5mm x 5mm) smart RGB LEDs onto a beautiful, round PCB with mounting holes and a chain-able design to create what we think quite an elegant NeoPixel board. Use only one microcontroller pin to control as many as you can chain together. Each LED is addressable as the driver chip is inside the LED. Each one has ~18m...
