he new 3G shield for Arduino enables the connectivity to high speed WCDMA and HSPA cellular networks in order to make possible the creation of the next level of worldwide interactivity projects inside the new "Internet of Things" era. The module counts also with an internal GPS what enables the location of the device outdoors and indoors combining standard NMEA frames with mobile cell ID triangulation using both assisted-mobile (A-GPS) and mobile-based (S-GPS) modes. You can also find our Audio/Video Kit to complete this 3G/GPRS Shield. Antennas not included.   You will need to update your firmware to play mp3. Uncompress and run it in a PC with Windows (emulated Windows not supported).   NOTE: The Arduino/Raspberry Pi jumper MUST be in Arduino position. The Raspberry Pi position should be used only if the shield is connected to a Raspberry Pi. A wrong position of this jumper can damage the 3G shield.
