Note: This product will EOL soon, please click here for Grove - Chainable RGB LED V2.0.
The Grove Chainable RGB LED is based on P9813 chip which is a full-color light source LED driver chip,can provide constant current drive and modulated output of 256 gray.Transmission by wire (DATA and CLK), built-in recycling, can enhance the transmission distance.
For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your using of the product.
This project shows how to connect a chainable LED to Grove.

Wiki of Grove - Chainable RGB LED
It would be good if you please, specify in the "Description", that it DOES include a grove cable.I thought It didn't included one, so I bought lots of cables. And when my package arrived, I noticed that It already had the needed cable included.
Thank you for your suggestion. we will add this in the description.
The LED light is always on when plugged in. How can I set it off all the time unless I turn if on?
It is a problem of your program, please modify it. And it does not have a default status.
The P9813 datasheet lists a company I cannot yet find. The datasheet indicates that the P9813 chip will drive qty 3 sets of RGB LED strings ( for a total of 9 strings ). Each string can be multiple LEDs. I cannot yet tell how much current each string c
Sorry for replying lately, Joanne. This grove module only ships with one RGB LED. Maybe the designer of it think it's neat for demonstration. According to its datasheet Answer by: admin on 2018-12-18 02:38:51
How bright is the LED on this board? Are there boards with multiple LEDs/driver chips pre-chained? e.g. a unit with 10 already chained up would be great.
Hi,the power of each LED is about 0.1w.And it has 9 driver chips worked if you combined 10 LEDs together.
How many of these can I chain to an arduino uno? Are the LEDs individually adressable?Hamish
Hi Hamish , the Maximum number LED is 1024 ,they doesn't have a individual adressable , but can be controlled individually.
