Round and black shape, this is great for making interesting project. 8/16/24 LEDs version available.
8/16/24 ultra bright smart LED NeoPixels are arranged in a circle with32/68/86 mm outer diameter.
The rings are cascaded connected – connect the output pin of one to the input pin of another. Use only one MCU I/O 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~18mAconstant current drive so the color will be very consistent even if the voltage varies, and no external resistors are required making the design slim.
Power supply: 4-7V DC
WS2812 use a single data line DO communication protocol, but a very timing-specified.
This ring board can be driven by AVR 8mhz MCU, such like AVR, PIC, arduino, etc.
WS2812 required a capacitor, but it is already designed on the board.
