Description
16 ultra bright smart LED are arranged in a circle with 68mm outer diameter. The rings are ‘chainable’ – connect the output pin of one to the input pin of another. Use only one microcontroller 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 ~18mA constant current drive so the color will be very consistent even if the voltage varies, and no external choke resistors are required making the design slim. Power the whole thing with 5VDC and you’re ready to rock.
The ring consists of 16 individually addressed RGB LEDs with an integrated controller. The module needs a single pin of the microcontroller, e.g. an Arduino. The LEDs are arranged at equal distances on the circumference with an outer diameter of 68 mm. Each consumes a current of 18 mA, which in this case gives a total value of approx. 290 mA. The ring can be powered with a voltage of 5 V.
Connection
The device has four terminals:- GND – module’s ground
- VCC supply voltage 18 mA current for one diode
- In the digital control signal from the microcontroller
- OUT – output to connect the next ring
Features:
- The control circuit and the LED share the only power source.
- The control circuit and RGB chip are integrated into a package of 5050 components, form a complete control of pixel point.
- Built-in signal reshaping circuit, after wave reshaping to the next driver, ensure wave-form distortion not accumulate.
- Built-in electric reset circuit and power lost reset circuit.
- Each pixel of the three primary colors can achieve 256 brightness levels, or 16M colors full-color display, and scan frequency not less than 400Hz/s.
- Cascading port transmission signal by a single line.
- Any two points the distance more than 5m transmission signal without any increase circuit.
- When the refresh rate is 30fps, cascade number is not less than 1024 points.
- Send data at speeds of 800Kbps.
- The color of the light was highly consistent
- Full-color module, Full-color soft lights a lamp strip.
- LED decorative lighting, Indoor/outdoor LED video irregular screen.
