I plan on running many strings of WS2811 chipped LEDs. A power supply will power the espruino, and the strings. The data-out of one string will feed into the data-in of another string. The strings of WS2811 commonly available have two ground wires coming out of each end. One of the grounds is mated with the data wire (see pic). I plan on using one of the grounds for each power injection, do I need to use the other ground for the data linking?
FYI: I'm cutting off the black connector that came on the strings and replacing with a waterproof connector. If I don't a ground with the data, then I'll just use a single pin connector for data.
Here is my plan. Does it look OK, or is it flawed?
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
