Reviews Led Constant Voltage Driver

24-bit LED Ring, 1pc 24 Bit WS2812 5050 RGB LED Ring Lamp Light with Integrated Drivers

  • Constant Current Drive: Each has a 18mA constant current driver, so the color is very consistent even if the voltage varies, and no external choke resistors are required to make the design slim. Amazing LED ring, you can use this LED ring lamp to DIY whatever you can think of.
  • Ideal for DIY: Each LED is addressable because the driver chip is inside the LED. So each pixel can have its own color and brightness as you wish.
  • Rings Connect: The LED ring lamp can be daisy-chained - connect the output pin of one to the input pin of the other.
  • Intelligent Protection: Use only one microcontroller pin to control as many as you can chain together, Intelligent reverse polarity protection, reverse power supply polarity will not damage the IC.
  • Bright LED: 24 ultra-bright smart LEDs are arranged in a circle with 3.3" (85mm) OD, power (5VDC recommended) and ground pins available.
