Technically the WS2811 is an IC that can be purchased on the market all by itself, with no LEDs. When the 5050 LEDs were added everyone called them a WS2811 because of this. Along the way, the WS2812(b) came around which were more technically correct, as this indicated the IC + LEDs all in one package.
The WS2811 strip light is an external IC programmable LED strip too with 3 pins with positive, negative, and data line. Usually made to DC12v. Regular is 30 LEDs, 48 LEDs, and 60leds per meter.
WS2812B LED strip lightis a built-in IC digital LED tape light with 3 pins including positive, negative, and data line. Voltage is DC5v input. Can be made to 30 pixels 60 pixels 74 pixels 96 pixels and 144 pixels per meter programmable strip light.
Today I am comparing the different normal addressable led strips, talking about their technical specifications, then I’m gonna help you figure out which one is the best-led strip lights for your project.
The most well-known chip currently is the ws2812b chip. This chip became very famous partly because Adafruit gave it the name “Neopixels” and made it available to the general public a few years ago.
It can do 30LEDs/M, 60LEDs/M, 144LEDs/m. Black and White PCB.
One Pixel with One LED, each LED can be cut. Detail as below, It with all WIFI controllers and Offline controllers.
Refresh Frequency updates reach 2 KHz, 5v compatible, and dual signal wires so that if one led gets damaged, the signal should still transfer to all other chips. (almost same with ws2815, but voltage different).
Any led broken will not affect another led unless two consecutive LEDs are broken.
It also isn’t a clockless chip with only three wires (+, -, data) but instead uses a 4 wire protocol (+, -, clock, data). The APA102 also has some advantages in regards to settable brightness and tune-able color spectrums. APA102 is also the brightest LED strip before, so if you need a lot of light output, this might be your LED chip! The APA102 can also be bought in full white variants giving you for instance warm white addressable LED strips.
A new chip from the creators of the WS2812B and compatible with the same protocol. The main improvements are a higher internal PWM frequency (around 2kHz), 12v compatible (5v logic signal), and dual signal wires (DI, BI, GND, 12V), so that if a chip gets damaged the signal should still reach all other chips. This causes ws2815 to use more watts than a ws2812b running the same pattern.
It is the cheapest addressable led strip, It is one signal cable, three cables (GND, DAT, 12V/24V), The voltage 12V/24V both available. RGBW and RGB color for more choice.
WS2811 IC uses pixel light and Amusement Pixel light widely.
