Yosoo Health Gear 24 Bits WS2812 RGB LED Ring Light 5050 RGB Lamp Panel Round LED Ring with Integrated Drivers

Features: - The rings are 'chainable' - connect the output pin of one to the input pin of another. - Use only one micro-controller pin to control as many as you can chain together! - Each LED is addressable as the driver chip is inside the LED. - Power the whole thing with 5VDC and you're ready to rock. - There is a single data line with a very timing-specific protocol. - Since the protocol is very sensitive to timing, it requires a real-time micro-controller such as an AVR, PIC, mbed, etc. - It cannot be used with a Linux-based microcomputer or interpreted micro-controller. - Our wonderfully-written library supports these pixels! As it requires hand-tuned assembly it is only for AVR cores but others may have ported this chip driver code so please google around. An 8MHz or faster processor is required. - Comes as a single ring with 24 individually addressable RGB LEDs assembled and tested.   Specifications: Voltage: 5V DC LED: 24-bit Inner Diameter: 5.3cm/2in Outer Diameter: 6.5cm/2.5in Weight: 8g(approx.)   Package Includes: 1 * LED Ring
