These chips are great, giving you 16 individually addressable LEDs on each ring, each capable of a huge amount of beautiful colours. I have loads of these left over from a project. All brand new in sealed packaging. There are 16 LED's on each light. Perfect for your next project using Arduino, ESP or Raspberry Pi. An absolute bargain at this price. 45mm external diameter and 31mm internal diameter. I will send you 20 rings for the price. Trying to declutter!
