Can you give me more details of this controller. For example, how many nodes can each channel handle, power supply recommendations. My intent is to make 17 bushes rgb dumb lights. Looks like I can use two of these to achieve that. Most bushes will be between 50 and 100 nodes, but a couple will take several hundred. Will the 100 count nodes listed on DLA wiki work with this controller? Sorry for the mass of questions. Just want to get where I need the best way.
The Ray Wu 27-channel controller controls 27 channels.
How I use it... and I believe most do the same... I group 3 channels together and connect them to the Red-Green-Blue wires on a dumb string. The 3 channels control a RGB dumb string. You can have 9 of these 3-channel groups.
In your example... if you had 17 bushes, each with a different RGB string to be controlled independently, you would use 2 Ray Wu 27-channel controllers... to provide control over 2x9 strings. ...you'd have 3 channels, or 1 string left over for a future need.
Why don't they call this a 9-string controller? maybe you would choose to control 27 single-color strings!
