BMT WS2812 16 LED Neopixel RGB Ring 60mm 5V

The BMT WS2812 16 LED Neopixel Ring is a compact programmable RGB LED module featuring 16 individually controllable 5050 RGB LEDs arranged in a circular 60mm ring. Each LED incorporates a control chip, allowing multiple LEDs to be controlled through a single data signal line.

Designed for Arduino, microcontroller, DIY lighting and interactive electronics projects, the module provides vibrant full-colour illumination with programmable brightness and colour effects. The integrated WS2811 control chip handles the LED data, helping simplify wiring and control compared with individually wiring each LED.

The module uses a serial data interface and supports data transmission speeds of up to 800Kbps. Both ends of the signal interface are provided for convenient connection to other compatible LED modules.

16 Individually Controllable RGB LEDs

The ring contains 16 high-brightness 5050 RGB LEDs, arranged evenly around the circular PCB.

The integrated control circuitry allows the LEDs to receive colour and brightness information through the serial data connection. This makes it possible to create patterns, animations, colour transitions and other programmable lighting effects.

Single I/O Control

One of the main advantages of the module is its serial control architecture. A compatible microcontroller can send data through a single I/O signal line to control the LED ring.

This helps simplify wiring and makes the module suitable for projects where available microcontroller I/O pins are limited.

Compatible control platforms may include suitable:

• Arduino boards
• Microcontroller development boards
• Robotics controllers
• DIY electronics projects
• Interactive lighting controllers

The controller must provide a compatible 5V LED data interface or suitable level shifting where required.

Built-In Signal Shaping

The LED module incorporates signal-shaping circuitry within the control chain. The supplied specifications indicate that signal distortion does not accumulate in the same way as with simple direct LED wiring, supporting stable operation when compatible modules are connected in series.

This makes the module suitable for creating larger programmable LED arrangements when the connected modules and controller are compatible.

RGB Colour Control

The RGB LEDs provide full-colour lighting by controlling the red, green and blue channels.

The supplied specifications indicate 256 brightness levels for each of the three colour channels, allowing a broad range of colour combinations and programmable lighting effects.

This can be used to create:

• Static colours
• Colour-changing effects
• Rainbow patterns
• Chasing effects
• Animated displays
• Status indicators
• Interactive lighting effects

Both-End Interface

The module provides an interface at both ends of the LED ring, allowing compatible modules to be connected directly in a chain.

This provides greater flexibility when designing larger LED installations or connecting multiple compatible LED modules.

Always observe the correct signal direction and connection markings when connecting modules together.

Compact 60mm Ring

The circular PCB has a diameter of approximately 60mm, making it suitable for projects where a compact circular lighting arrangement is required.

The ring format can be incorporated into enclosures, control panels, displays, wearable projects, decorative lighting and interactive installations.

Applications

The BMT WS2812 16 LED RGB Ring can be used for:

• Arduino projects
• Microcontroller projects
• DIY LED lighting
• Neopixel-style projects
• Robotics
• Interactive displays
• Wearable electronics
• Decorative lighting
• Model making
• Status indicators
• Gaming and PC lighting projects
• Educational electronics
• Light effects and animations
• Custom LED installations

Typical Connection

A typical setup consists of:

5V Power LED Ring

Microcontroller Data Output LED Data Input

When connecting additional compatible rings or modules, the data output can be connected to the data input of the next module.

Always verify the module's power, ground and data connections before applying power.

Power Requirements

The module is specified as a 5V LED module. Use a suitable regulated 5V power source and ensure that the power supply is capable of supplying the current required by the LEDs and any additional modules connected to the system.

Power requirements will vary depending on the number of LEDs illuminated, brightness settings and colour combinations.
