Hello I am using a Nodemcu to control a bunch of WS2811 LEDs and it works perfectly, until I want to extend a section by 2-3m and the furthest section starts to flash badly. If I keep the power the same length but shorten the data signal to 20 cm flashing stops. So in my mind this means the data s…
