![Large 40 RGB LED Ring WS2812-Compatible 5050 125 mm](http://chicagodist.com/cdn/shop/products/Screen_Shot_2018-03-13_at_11.01.04_AM_812x700.jpg?v=1594335009)
These are our own individually-addressable RGB LED rings. They are connected and driven the same way as Adafruit NeoPixel Rings.
Connections:
- DI - Data In from microcontroller
- 5V - 5 V power
- GND - to Ground
- DO - Data Out, to chain to next set of LEDs' DI connection
Connections are made to 2.54 mm / 0.1" pitch solder pads. Care should be taken not to support the LED ring from the solder pads.
Inside diameter approximately 107 mm, outside diameter approximately 125 mm. There are four 2 mm diameter mounting holes in the ring spaced at 90° intervals.
