A freeing asked me to help I’m light his vertical wind generator at his house. Which will require some longer runs from the controller to the led strips.
I found this guy “blinky lights” has solved the problem pretty cleanly for a very similar project and wanted to see if I could just buy some of the boards. Does anyone know how I can get in contact with him? I couldn’t find contact details on the blog etc.
I can confirm that the rs422/rs485 transceivers work well for this. Check the max data speed, these vary and have a tradeoff with impedance matching (slower ones work better on mismatched impedances).
You can get cheap modules on Amazon. These are rated for 2.5mbps and will work for ws2812 or expander data!
