ALLNET 4duino Neopixel-rengas (ALL-4duino-Ring)

The ALLNET 4duino Neopixel Ring is a compact 12-LED RGB ring based on the WS2812B addressable LEDs. Designed for Arduino, Raspberry Pi, ESP32/ESP8266, and other microcontrollers, it allows individual control of each LED for stunning lighting effects. The ring operates at 5V DC and features a daisy-chainable design for expanding your projects.

Advantages

Easy to integrate with popular microcontroller platforms; each LED is individually addressable for full-color animations; low power consumption with maximum 720 mA at full white; compact 44 mm diameter fits into small enclosures; daisy-chainable for larger displays.

Suitable for

• Arduino and compatible boards
• Raspberry Pi GPIO projects
• ESP32/ESP8266 IoT devices
• Wearable electronics and lighting effects
• Educational STEM kits

Recommendations

For best results, use with a 5V power supply capable of at least 1A. A level shifter may be required for 3.3V logic microcontrollers. Always connect a capacitor (e.g., 1000 µF) between VCC and GND to smooth power.
