4 2011-07-08 SparkFun <p> <strong>D</strong><span style="font-weight: bold;">escription: </span>The Cellular Shield for Arduino includes all the parts needed to interface your Arduino with an <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=9533" name="" target="_self">SM5100B</a> cellular module. This allows you to easily add SMS, GSM/GPRS, and TCP/IP functionalities to your Arduino-based project. All you need to add cellular functionality to your Arduino project is a SIM card (pre-paid or straight from your phone) and an antenna and you can start sending Serial.print statements to make calls, send texts and serve web pages!</p> <p> &nbsp;The main components of the Cellular Shield are a 60-pin <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=9535" name="" target="_self">SM5100B connector</a>, a <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=548" name="" target="_self">SIM card socket</a>, and an SPX29302 voltage regulator configured to regulate the Arduino&#39;s raw voltage to 3.8V. The board&#39;s red LED indicates power. The Arduino&#39;s reset button is also brought out on the shield.<br /> <br /> Two solder jumpers on the board allow you to select which serial pins interface with the cellular module - software (D2, D3) or hardware (D0, D1). There is also a 5-pin, 0.1&quot; spaced header with connections for microphone inputs and speaker outputs. Headers are not soldered on, we recommend the <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=9280" name="" target="_self">6</a> and <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=9279" name="" target="_self">8-pin stackable headers</a>.<br /> <br /> The SM5100B cellular module <span style="font-style: italic;">is</span> included with this product, however an antenna is not. It is pre-configured to 9600bps.<br /> <br /> <span style="font-weight: bold;"><span style="font-weight: bold;">Documents:</span></span></p> <ul> <li> <a classname="" href="http://www.sparkfun.com/datasheets/DevTools/Arduino/cellular%20shield-v12.pdf" name="" target="_blank">Schematic</a></li> <li> <a classname="" href="http://www.sparkfun.com/Code/Cellular_Shield_Passthrough.zip" name="" target="_blank">Sample Sketch</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/CellularShield/SM5100B%20Datasheet.pdf" name="" target="_blank">SM5100B Datasheet</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/CellularShield/SM5100B%20AT%20Command%20Set.pdf" name="" target="_blank">SM5100B AT Command Set</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/CellularShield/SM5100B%20SMS%20App%20Note.pdf" name="" target="_blank">SM5100B SMS App Note</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/CellularShield/SM5100B%20TCPIP%20App%20Note.pdf" name="" target="">SM5100B TCP/IP App Note</a></li> <li> <a href="http://tronixstuff.wordpress.com/2011/01/19/tutorial-arduino-and-gsm-cellular-part-one/" target="_blank">Arduino Tutorial</a></li> </ul> Arduino Cellular Shield http://www.sparkfun.com/products/9607 Cell Cellular SM5100 Cellular Shield MIC_N
