The Xadow Duino is specially designed for building up awesome Lighting Devices using the most popular RGB LED WS2812b. Based on the MCU ATmega32u4 and the built-in micro USB, Xadow Duino allows you to either control the RGB LEDs directly from the software in RePhone Kit Create, or program the board with Arduino IDE to make it work dependently. ![enter image description here][1] Unlike any other add-on modules, this board also has its own battery socket (JST1.0 type), so you can power it in many ways: Via 5V USB (if the battery is connected, it would also charge the battery simultaneously ) Via 3.7V Lipo battery Via breakout pins Via Xadow GSM+BLE Include Xadow Duino* 1 FPC Cable 11 PIN * 2 LED strip * 1 Features: Able to work like an Arduino Plug-and-play if connected with RePhone Kit Create Open source and modular design Slim and small Specially designed for WS2812B Built-in 11PIN Xadow Connectors for full flexible connection with other Xadow Modules Stackable, chainable and sewable with other Xadow Modules Perfect choice for LED lovers Specification: Microcontroller: ATmega32u4 Power Supply: 5V via USB, current draw is 1.5A at Max 3.3 – 4.2V via battery socket, current draw is 1.5A at Max 3.3 – 6V via breakout pins, current draw is 500 mA at Max 3.3 – 4.2 V via Xadow GSM+BLE, current draw is 500 mA at Max Charging Current: 500 mA Flash Memory: 32 KB (ATmega32u4) of which 4 KB used by bootloader SRAM: 2.5 KB (ATmega32u4) EEPROM: 1 KB (ATmega32u4) Clock Speed: 16 MHz Connector: 2 x 11 PIN Xadow Connector Bonding pads for RGB LED WS2812b Interfaces: Interface with Xadow GSM+BLE through I2C (7-bit address 0x23) Dimension: 25.37mm X 20.30mm / 1’’ X 0.8’’ From：For more detail, please visit: http://www.seeedstudio.com/item_detail.html?p_id=2556 Xadow Duino The Xadow Duino is specially designed for building up awesome Lighting Devices using the most popular RGB LED WS2812B.

Monochrome, 2 Marquee, 3. Rainbow ![enter image description here][3] Set If This Then That In the ‘If This Then That’ you can set different conditions to trigger the Xadow Duino to light up the WS2812B in a specified mode. Program it with Arduino IDE You can also do some coding with the Arduino IDE to customize your light sources. There are many good projects on the internet, wondering how other people DIY cool lighting stuff?
