RainbowBit - Serial RGB LED

  • Availability:
  • Product Code: BB-ARGB
We have been searching for serial controllable LED for quite some time and finally we found it. This is Serial Controlled RGB LED module. The module is premounted with WS2812B SMD LED and tested. The WS2812B is an intelligent and serially controlable LED light which comes with control and driver IC integrated in the RGB SMD LED package. It includes intelligent digital port data latch and signal reshaping amplification drive circuit. Also include a precision internal oscillator and a programmable constant current control part, effectively ensuring the pixel point light color height consistent.

For comparison, there are two types of serial controlled RGB LED, WS2812 and WS2812B. This module is mounted with WS2812B (latest version). You can check out the comparison in the attachment.
The LED offers low driving voltage, environmental protection and energy saving, high brightness, scattering angle is large, good consistency, low power, long life and other advantages. The control chip integrated in LED above becoming more simple circuit, small volume, and convenient installation.
We name this LED module RainbowBit, please download the example code for Arduino to get started. We are preparing getting started guide.
Note: If you need RainbowBit in strip form, please check out RainbowStrip which come in 1 meter, 30 pcs RainbowBit with silicon cover.

Q & A (5)
Can I use this with raspberry pi? If yes, can you provide a tutorial? ( Vento, 19/10/2018 )
Hi, this Rainbowbit signal protocol is not supported by Raspberry Pi . Thanks.
Hi, can you give me an example program for controlling two of this LED by using Arduino Micro? ( AHMAD RAZELAN RASHID, 20/03/2018 )
Hi, you can refer to Make Your Own Colorful Plate For Your Home tutorial. For further questions, please visit to our technical forum for similar question or post your question there, as this session is only for short inquiry. Thanks.
Is this product RoHs compliant? ( Yelo, 04/05/2017 )
No, this product is not RoHs compliant. Thanks.
I am planning to make a led grow light which runs on battery with about 8 of this RainbowBits. Will I need a led driver and heat sink for that? Thank you. ( Walter, 25/09/2015 )
Nop, one of the features is the driver is embedded in the LED itself.
Hello, Can this we control the brightness of this RGB light? Thanks, ( Kappa, 07/01/2015 )
Yes, you can! Please check the tutorial for sample code for more details.
