Interface Description


Color Function
Red VCC, connect to the positive pole of the 5V power supply
Green DATA, data input/output (male input, female output)
White GND, connect to the negative pole of the 5V power supply

Protocol Description

WS2812B adopts a single-wire communication mode and sends signals in return-to-zero code. After the chip is powered on and reset, it receives the data from the DIN terminal. After receiving enough 24 bits, the DO port starts to forward the data to the next chip to provide input data. Before forwarding, the DO port has been pulled low. At this time, the lamp beads will not receive new data, and the built-in RGB chip will display different brightness according to the different duty cycle signals generated after receiving the 24-bit data. If the DIN input signal is RESET, the chip will send the received data to display, the chip will receive new data after the end of the signal, and after receiving the starting 24-bit data, data will be forwarded through the DO port before the lamp does not receive the RESET code, the RGB brightness remains unchanged. When the low-level RESET code above 200us is received, the RGB chip inside the lamp bead will show different brightness according to the different duty cycle signals generated after the 24-bit data just received.

Data Transmission

Note: D1 is the data sent from MCU, D2, D3, and D4 are the data automatically shaped and forwarded by cascaded circuits.

24-bit data structure

Note: Data in high bits are sent first and follow the RGB order.

Current/Power Rewuirements

  • The maximum power per meter of this product is about 18W, and the operating voltage is 5V, so the maximum current per meter is about 3.6A.
  • Therefore, when using the selected power supply, it should not be less than 1.25 times the maximum power.
  • If multiple light strips are cascaded, it is recommended to add the voltage every 300 lights.
