Picture of Arduino Wireless SD Shield Tutorial
As the name implies, the Arduino Wireless SD shield serves two functions. Foremost, this shield allows you to easily interface with Xbee transceiver modules to create mesh networks, and other wireless devices. Secondly, the micro SD socket allows you to store and access a large amount of data. Whether using these functions by on their own or together, this chip greatly enhances the capabilities of a standard Arduino. The best part about this shield is how easy it is to use. In no time flat, you can have its various components up and running.

Step 1: Plug in the Xbee

Plug in your Xbee modules in order to use the shield as a wireless transceiver.

Make sure the module's pointy end is lined up with the edge of the board.

If you are using the shield for wireless data transfer, you will need two or more of them.

Step 2: Plug it in

Plug your shields into your Arduinos.

Step 3: Features

Picture of Features
The wireless SD shield supports Xbee modules. These modules allow for easy wireless serial communication. A standard module has the range of 100 - 300 feet.

It also boasts a micro SD socket. This can easily be interfaced with the Arduino SD library. Unfortunately, this library does not come bundled with the Arduino development environment, so you will have to set it up yourself.

The shield also boasts a perfboard grid for prototyping your own circuit, and a micro switch for toggling between the USB port and micro SD port.

For more technical information visit its official Arduino page.

Step 4: Program the receiver

Plug one of the Arduinos into the computer. Make certain the micro switch is toggled to the "USB" option.

Dear friends, thanks for the tutorial.

Anyway I would like to ask some additional help.

In my sketch I need to open a file from the SD in order to get two values (void loop) from a list, then I get two values from my sensor, and in the last step I want to save these two values into another or even same file into the SD. The problem is that if I close the SD file (a .txt) to switch the SD sate from READ to WRITE every time I return to the SD to read from the list I will be at the first data from the list, and I would like to continue reading the list.....

1. open SD txt file (there is a list of data: 1. sassa 2.dadad 3.ffsfsf 4.fdfdf

2. get first value of the list: sassa (READ SD)

3. get value from my sensor: s = 122

4. save that value into the file (WRITE SD).

so my question is: how could I avoid to always return to sassa, into the first list position each time I acces the SD file, just because I have closed the SD file in order to be allowed to switch to WRITE the SD ?

many thanks!

Great tut !
Question: I see that on the image with the SD card that you're using a 4GB. I read that the maximum SD size is supposed to be 2GB. Did you try it successfully with a 4GB ?

Awesome! I was considering using a xbee zig bee pro for a model airplane/drone i am working on. Supposedly this particular xbee has a range of 2 miles outdoors line of sight. I want to use this shield to run the xbee during flight and to record flight data.
However, i cannot figure out how many pins the shield uses? This will determine if I need an uno or a mega
Also! Looks like the xbee I have chosen draws about 205mA in transmit and 50mA in receive mode. Do you think this board adds much to that? I don't really know how much current the SD card dongle consumes...

Also, I assume (whoops) that I can program the xbee to switch between transmitter and reciever mode? This is why I want a transceiver instead of a normal model airplane radio. I need to send and receive data from the plane

What Xbee modules did you use and did you have to configure them in any way before using them?

I used these:

No extra configuration necessary. I just plugged everything in and it worked.

what is its maximum range (in meter of feet) ??
Roughly 100ft indoors 300ft outdoors. There are 3 types of series 1 xbees so the one with the antenna probably has the best range. Sparkfun has a great information page http://www.sparkfun.com/tutorials/257
