DFRobot Neopixel Ring 16x WS2812 RGB LED

The ring from DFRobot carries 16 WS2812 RGB LEDs that are addressed individually via a single data line. Each LED shows 16 million colours, creating colour gradients, chaser lights or a clock. Several rings can be cascaded: the OUT output of the first ring is connected to the IN input of the next one. It is programmed with Arduino IDE, Mind+ or MakeCode for micro:bit.

It is powered with 3.3 to 5 V. At 5 V on a 3.3 V board such as ESP32 or ESP8266, a Logic Level Converter 2-Channel 5V / 3.3V is recommended for the data line.

Note: The connection cable can be converted to male pins with a Dupont cable M-M, so that it also fits an Arduino UNO.

Recommended Accessories:

• Dupont Cables M-M 10cm 20 Pieces
• Logic Level Converter 2-Channel 5V / 3.3V
• 5V DC 5000mA Power Supply AC/DC Adapter 5.5mm/2.1mm Plug Waveshare
• DC Female Barrel Jack 5.5mm / 2.1mm with Spring Clamps

Features:

• 16 WS2812 RGB LEDs, individually addressable, 16 million colours
• Control via one data line
• IN and OUT connectors with PH2.0 3-pin: D (data), + (VCC), - (GND)
• Cascading of several rings from OUT to IN, this requires a cable with PH2.0 3-pin on both ends (not included)
• Power supply 3.3 to 5 V
• Programming with Arduino IDE, Mind+ and MakeCode

Application Examples:

• LED clock, compass or countdown timer
• Colour effects for robots, models and decoration
• Status display for projects with micro:bit or Arduino
