The WS2812B 4x4 RGB LED Module features a circular development board with built-in full-color driving lights and a sleek round black design. It includes 16 ultra-bright NeoPixel LEDs arranged in a circular PCB with a 68mm outer diameter. These RGB ring lights can be easily connected by cascading them through the output pin (DI) to the input pin (DO), allowing multiple modules to be controlled by a single chip.

Each LED is integrated with a driver chip, making the lights smart and addressable. The module uses a constant current drive of -18mA per LED to ensure uniform color display, even when voltage fluctuates. No external current-limiting resistors are needed, making the design compact and efficient. A 5V power supply is required to operate the RGB ring.

The module supports single-wire communication to reduce I/O pin load and uses the WS2812B driver chip. The circuit requires only a single capacitor to function, simplifying the design. Additionally, the LEDs can be cascaded through the Dout input port, enabling unlimited expansion without limitations on module shape.

Note: The module marked with HW-223 has the same functionality.

Features:

• The LED and control circuits share a single power source.
• The control circuit and RGB chip are integrated into 5050 packages, providing full pixel control.
• Includes a built-in signal reshaping circuit that prevents waveform distortion during signal transmission.
• Features both an electric reset and a power loss reset circuit.
• Each pixel can display 256 brightness levels per primary color, offering a full range of 16 million colors with a scan frequency of at least 400Hz/s.
• Cascading is done via a single data line.
• Signal transmission distance between any two points can exceed 5m without additional circuits.
• At a refresh rate of 30fps, up to 1024 modules can be cascaded.
• Data is transmitted at 800Kbps.
• The light color consistency is excellent.
• Ideal for full-color decorative lighting, including indoor/outdoor LED displays and irregular screens.
