WS2812 Neopixel Addressable RGB LED-3535

WS2812 Neopixel Addressable RGB LED-3535 is a high-performance, intelligent light source that integrates a control circuit and an RGB chip directly into a compact 3535 surface-mount package. This advanced component allows users to control each individual LED in a chain using only a single data line, making it a cornerstone for modern lighting projects. Furthermore, the internal driver handles pulse-width modulation (PWM) for each color channel, which ensures consistent brightness and a spectrum of over 16 million colors. Consequently, designers can create complex visual effects without the need for massive wiring looms or multiple driver chips. Therefore, you can easily scale your lighting designs by simply daisy-chaining these modules together to achieve vibrant, synchronized displays.

Key Features:

• Individually Addressable: Each LED contains a unique integrated circuit, allowing for independent control of color and brightness via a serial protocol.
• Single-Wire Communication: The protocol uses a single signal line to transmit data, which significantly reduces the complexity of PCB routing and assembly.
• Integrated Control Circuit: Built-in signal reshaping circuits ensure that data distortion does not accumulate, even in long-distance transmissions.
• 3535 Form Factor: The smaller footprint compared to the standard 5050 package enables higher pixel density for high-resolution LED matrices.
• Cascadable Design: The output of one LED connects directly to the input of the next, facilitating the creation of long strips or large-scale arrays.

Technical Specifications:

• Supply Voltage (V_DD): +3.5 V to +5.3 V
• Input Voltage (V_I): −0.5 V to V_DD +0.5 V
• Data Transfer Rate: 800 Kbps (High-speed mode)
• PWM Frequency: ≥ 400 Hz/s
• Color Depth: 24-bit (8-bit per channel for Red, Green, and Blue)
• Operating Temperature Range: −25°C to +80°C
• Luminous Intensity: Red (280-450 mcd), Green (600-1100 mcd), Blue (150-280 mcd)

Mechanical Specifications:

• Package Type: SMD 3535 (Surface Mount Device)
• Encapsulation: Clear Silicone or Epoxy Resin
• Terminal Material: Gold-plated Copper
• Moisture Sensitivity Level: MSL 3

Dimensions:

• Package Length: 3.5 mm
• Package Width: 3.5 mm
• Package Height: ≈ 1.4 mm
• Pin Pitch: ≈ 0.9 mm

Pinout and Wiring:

• Pin 1 (VDD): Connect to the positive power supply (+5 V recommended).
• Pin 2 (DOUT): Data Output. Connect this to the DIN pin of the subsequent LED in the series.
• Pin 3 (VSS/GND): Ground connection. Ensure a common ground with your microcontroller.
• Pin 4 (DIN): Data Input. Connect this to the microcontroller signal pin or the DOUT of the previous LED.
• Wiring Note: However, you should always place a 100 nF decoupling capacitor near the VDD pin to filter power supply noise and ensure stable operation.
