Features and Benefits
The control circuit and the LED share the only power source.
The control circuit and RGB chip are integrated in a 5050 components, to form an external control pixel.
Using the built-in signal reshaping circuit to achieve the signal waveform shaping, and no distortion of waveform of
signal takes place.
Built-in power-on reset and brown-out reset circuits.
The gray levels of each pixel are of 256 levels, which achieves “256*256*256=16777216” full-color display, and
the refresh frequency reaches to 2KHz/s.
Serial cascade interface, data receiving and decoding depend on just one signal line.
Dual-signal wires version, signal break-point continuous transmission.
Any two point the distance more than 3m transmission signal without any increase circuit.
When the refresh rate is 30fps, cascade numbers are far more than 1024 points.
Data transmitting at speeds of up to 800Kbps.
Good color consistency reliability, high cost-effective.
Applications
Guardrail tube series, point light display series, flexible/rigid strips series, module series applications.
Lighting stage costumes, innovative gadgets or any other electronic products.
General description
WS2813 is an intelligent control LED light source that the control circuit and RGB chip are integrated in a package
of 5050 components. Its internal include intelligent digital port data latch and signal reshaping amplification drive circuit.
Also include a precision internal oscillator and a 12V voltage programmable constant current control part,
which achieves highly consistent color effect.
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port receive
data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data which
reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port. After
transmission for each pixel, the signal to reduce 24bit. Every pixel adopts auto-reshaping transmit technology, making
the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal transmission.
The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if DIN
do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's damage
does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after power-off.
Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.
250us or more of reset time, it won’t cause wrong reset while interruption, it supports the lower frequency and
inexpensive MCU.
There’re in a choice of 18mA or 5mA current version, and also in a choice of high brightness or cost-effective version.
That is to say, WS2813 is provided with four versions.

Repairing instruction
Normally, it can’t be repaired after reflow. You need to use double-ended solder iron and make sure that whether it will
do damage to the LEDs’ characteristics when repairing is inevitable.
Storing and Transporting
1．Scope of application
Front side up, moisture-proof and waterproof, no extrusion, no collision and no vibration.
2．Storage and its period
1Room temperature sealed storage: 20℃～30℃, 40%～60%RH, product is valid for ONE month.
2Moisture-proof sealed storage: 20℃～30℃, 25%～60%RH, product is valid for THREE month.
3Use up with 2 hours after removing from packages.(Environmental conditions for temperature <30℃,
relative humidity<60%)
Dehumidification
We would recommend to do dehumidification if they exceed the valid storage period of products or dampened due to
other reasons.
Dehumidification Method: 70℃-75℃/22±2 Hours
Electrostatic Protection
LED is an electrostatic sensitive component, although the LED products are with excellent anti-static ability, they will
cause a certain damage by any electrostatic discharge. By taking some electrostatic measures to avoid the damages when
using the LEDs, such as wearing anti-static gloves and anti-static bracelet, etc..
Precautions
Pressing the colloid surface will affect the reliability of LED because the LED is advanced silicone-gel. And therefore
precautions should be taken to avoid the strong pressure on the component. It’s proper to make the LED be used in safe
condition when using a suction nozzle. Silicon packing with soft and elastic, it greatly reduces thermal stresses and
unable to bear external mechanical forces. Therefore, preventive measures should be taken in process of manually
handling.
