Review on 🌈 Rextin WS2811 Pixels Digital Addressable LED String Lights: Waterproof, RGB Full Color, 12mm, DC 12V - (DC12V 50pcs) by Jennifer Davis

Good product at a good price. This is for a 5V powered filament Installation: 5V/3A wall battery attached to power strip, UNO and Neopixel library and in some sketches. They worked without any problems. Fastled - #define LED_TYPE WS2812B or like WS2811 (both worked with this band) #define COLOR_ORDER GRB - Fix for this band #define NUM_LEDS 50Neopixel - Would not work if set to 400KHz or RGB. // Parameter 1 = number of pixels in the strip // Parameter 2 = pin number (most of these are valid) // Parameter 3 = pixel type flags, sum as needed kHz (classic 'v1' (not v2) FLORA pixels , WS2811 driver) // NEO_GRB pixels are connected to the GRB bitstream (most NeoPixel products) // NEO_RGB pixels are connected to the RGB bitstream (v1 FLORA pixels, not v2) Adafruit_NeoPixel strips = Adafruit_NeoPixel (50, PIN, NEO_GRB + NEO_KHZ 800); are the correct settings for this step. WS8211 strip (50 pixels) attached WS2812B strip (30 pixels).
