ws2811 pixel node_2 Q&A

Q: How many ws2811 pixel nodes can be connected to one controller?

A: The number of pixels that can be connected to one controller depends on the type of controller used. For example, a Type-C controller can support up to 512 pixels, which are 256 RGB pixels. On the other hand, a Type-D controller can support up to 2048 pixels. This translates to 1024 RGB pixels. It is important to note that the number of pixels that can be connected to a single controller also depends on the power supply. In most cases, it is recommended not to exceed 100 nodes per output channel.

Q: Are the pixel nodes waterproof?

A: The pixel nodes are waterproof, but only the ones with a black wire. These pixel nodes have an IP67 rating, which means they are dust-tight and protected from temporary immersion in water. The waterproof rating of the pixel nodes without black wires is IP68. While these pixel nodes are not completely waterproof, they are water-resistant.

Q: What is the maximum length of a ws2811 pixel node string?

A: The maximum length of a pixel string depends on the type of pixel. For example, the maximum length of a string of ws2811 pixel nodes is 5 meters. On the other hand, the maximum length of a string of ws2813 pixel nodes is 10 meters. It is important to note that the maximum length also depends on the power supply voltage. For instance, when using a 12V power supply, the maximum length can be up to 10 meters. However, if using a 24V power supply, the maximum length can be up to 20 meters.
