This standard sheild for WRTnode is directly stackable with the WRTnode Mini OpenWRT Dev Board. WRTnode (A Mini OpenWRT Dev Board) uses a MTK MT7620N 580MHZ MIPS CPU, and is powerful in both interface and functionality. But expanding its interface with jumper wires is troublesome since there are only pin headers and Micro USB available onboard. This standard shielf for WRTnode not only expands GPIO, SPI, I2C, etc., but also expands the number of USB interfaces to four, at the same time providing a 100m Ethernet interface. Now it's your choice to have messy spaghetti or just one shield on your board. WRTnode (A Mini OpenWRT Dev Board) is a high performance CPU, low power consuming, cheap and small dev board that can run OpenWRT OS and also easy to port all open source software of Linux. OpenWRT is a Linux distribution for embedded devices, the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned. Today, more and more devices could connect to internet, named Internet of Things. The WRTnode (A Mini OpenWRT Dev Board) is a small node which could connect internet all by itself and do complicated tasks. Such as track a cat running over, identify what you are saying and twitter it, check email and pronounce for you, learn how your room layout and find garbage to sweep while streaming camera video to you over internet. Just to name a few. Note: 
- Be sure to plug the WRTnode into the shield as shown in the picture, Be sure DO NOT go wrong direction.
- For the power we recommend a 5V USB-interface adapter higher than 1000mA, when more USB devices plugged in, we recommend a 2A or 2.5A adapter, such as your ipad one.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- RJ45
- The common plug and socket style used for wired Ethernet network cables. If a board has an RJ45 connector, you can usually plug it into standard Ethernet cabling without making a custom connector.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
