4 2011-07-08 SparkFun <p> <b>Description: </b>The Bluetooth Mate is very similar to our BlueSMiRF modem, but it is designed specifically to be used with our <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=9219" name="" target="_self">Arduino Pros</a> and <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=9266" name="" target="_self">LilyPad Arduinos</a>. These modems work as a serial (RX/TX) pipe, and are a great wireless replacement for serial cables. Any serial stream from 9600 to 115200bps can be passed seamlessly from your computer to your target.</p> <p> Bluetooth Mate has the same pin out as the FTDI Basic, and is meant to plug directly into an Arduino Pro, Pro Mini, or LilyPad Mainboard. Because we&#39;ve arranged the pins to do this, you cannot directly plug the Bluetooth Mate to an FTDI Basic board (you&#39;ll have to swap TX and RX).</p> <p> The RN-42 is perfect for short range, battery powered applications.&nbsp; The RN-42 uses only 26uA in sleep mode while still being discoverable and connectable.&nbsp; Multiple user configurable power modes allow the user to dial in the lowest power profile for a given application. If you need longer range, check out the Bluetooth Mate Gold.</p> <p> The Bluetooth Mate has on-board voltage regulators, so it can be powered from any 3.3 to 6VDC power supply. We&#39;ve got level shifting all set up so the RX and TX pins on the remote unit are 3-6VDC tolerant. <span style="font-weight: bold;">Do not</span> attach this device directly to a serial port. You will need an <a href="http://www.sparkfun.com/products/449" target="_blank">RS232 to TTL converter circuit</a> if you need to attach this to a computer.</p> <p> Unit comes without a connector; if you want to connect it to an Arduino Pro, we&#39;d suggest the <a classname="" href="http://www.sparkfun.com/commerce/product_info.php?products_id=9429" name="" target="_self">6-pin right-angle female header</a>.</p> <p> <strong>Note: </strong>The hardware reset pin of the RN-42 module is broken out on the bottom side of the board. This pin is mislabeled as &#39;PIO6&#39;, it is actually PIO4. Should you need to reset the Mate, pull this pin high upon power-up, and then toggle it 3 times.</p> <p> <span style="font-weight: bold;">Features</span><b>:</b></p> <ul> <li> Designed to work directly with Arduino Pro&#39;s and LilyPad main boards</li> <li> FCC Approved Class 2 Bluetooth<sup><font face="Tahoma, sans-serif"><b>&reg; </b></font></sup>Radio Modem!</li> <li> Low power consumption : 25mA avg</li> <li> Hardy frequency hopping scheme - operates in harsh RF environments like WiFi, 802.11g, and Zigbee</li> <li> Encrypted connection</li> <li> Frequency: 2.4~2.524 GHz</li> <li> Operating Voltage: 3.3V-6V</li> <li> Serial communications: 2400-115200bps</li> <li> Operating Temperature: -40 ~ +70C</li> <li> Built-in antenna</li> </ul> <p> <span style="font-weight: bold;">Dimensions: </span></p> <ul> <li> Board: 1.75x0.65&quot;<br /> <span style="font-weight: bold;"> </span></li> </ul> <p> <b>Documents:</b> <a href="http://www.sparkfun.com/datasheets/RF/BlueSMiRF_v1.pdf" target="_blank"><br /> </a></p> <ul> <li> <a classname="" href="http://www.sparkfun.com/datasheets/Wireless/Bluetooth/ArduinoBluetoothMatev13.pdf" target="_blank">Schematic</a></li> <li> <a href="http://www.sparkfun.com/datasheets/Wireless/Bluetooth/ArduinoBluetoothMatev13.zip" target="_blank">Eagle Files</a></li> <li> <a classname="" href="http://www.sparkfun.com/datasheets/Wireless/Bluetooth/rn-bluetooth-um.pdf" name="" target="_blank">RN-42 AT Command Set</a><a href="http://www.sparkfun.com/datasheets/RF/RN_BlueportII-ref-guide.pdf" id="Roving Networks Bluetooth Command Set" name="Roving Networks Bluetooth Command Set" target="_blank"></a></li> <li> <a classname="" href="http://www.rovingnetworks.com/documents/RN-41.pdf" name="Roving Networks Bluetooth module datasheet" target="_blank">Roving Networks Bluetooth<sup><font face="Tahoma, sans-serif"><b>&reg;</b></font></sup> module datasheet</a><br /> <a href="http://www.sparkfun.com/datasheets/RF/RN-24-guide.pdf" id="Roving Networks RN-24 Usage Guide" name="Roving Networks RN-24 Usage Guide" target="_blank"></a></li> <li> <a href="http://www.sparkfun.com/tutorials/67" target="_blank">Check out our Bluetooth Tutorial</a></li> </ul> Bluetooth Mate Silver http://www.sparkfun.com/products/10393 Bluetooth Mate Wireless Wireless Bluetooth RTS_5V
