It got 256 WS2812b RGB LEDs soldered, and found that at the end of chain, LEDs start looking dimmed (they become orange, like loose blue and some green), like not much power left, especially if they all white. It is plugged to espruino (power, data, ground). As I understand I should move power and ground to external source?
