Modulo Adafruit FONA 808 – Mini Cellular GSM / GPRS + GPS

Cellular + GPS tracking, all in one? Oh yes! Introducing Adafruit FONA 808 MiniGSM + GPS, an all-in-one cellular phone module with that lets you add location-tracking, voice, text, SMS and data to your project in an adorable little package.

This module measures only 1.75″x1.6″ but packs a surprising amount of technology into it’s little frame. At the heart is a powerful GSM cellular module (we use the latest SIM808) with integrated GPS. This module can do just about everything.

  * Quad-band 850/900/1800/1900MHz – connect onto any global GSM network with any 2G SIM.
  * Fully-integrated GPS (MT3337 chipset with -165 dBm tracking sensitivity) that can be controlled and query over the same serial port.
  * Make and receive voice calls using a headset or an external 32Ω speaker + electret microphone.
  * Send and receive SMS messages.
  * Send and receive GPRS data (TCP/IP, HTTP, etc.).
  * PWM/Buzzer vibrational motor control.
  * AT command interface with «auto baud» detection.

Here’s the GPS specifications:

  * 22 tracking / 66 acquisition channels.
  * GPS L1 C/A code.
  * Sensitivity: Tracking: -165 dBm, Cold starts : -147 dBm.
  * Time-To-First-Fix: Cold starts: 32s (typ.), Hot starts: 1s (typ.), Warm starts: 5s (typ.).
  * Accuracy: approx 2.5 meters.

Sounds delicious, right? So we plated this fine module onto a little breakout with all the extras you need to make your next project shine:

  * Onboard LiPoly battery charging circuitry so you can take your project on the go. Use any 500mAh+ LiPoly or LiIon battery and recharge over the MicroUSB when necessary. Two LEDs let you know when its charging and done.
  * Standard 4-pole TRRS headphone jack. Use any ‘Android’ or ‘iPhone’-compatible headset with mic.
  * Breakouts for external 32Ω speaker and electret mic if you don’t want to use a headphone.
  * Level shifting circuitry so you can run it with 2.8V to 5V logic.
  * Vibrational motor (buzzer) driver so you can have noiseless notifications.
  * uFL connections for external antennas.
  * Indicator LEDs for power and network connectivity.
  * Standard SIM slides into the back.


On its own, this module can’t do anything. It requires a microcontroller to drive it! We suggest and use an Arduino, Raspberry Pi or any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.


* Nota: Es necesario conectar una batería lipo de mínimo 500mAh ( se recomienda de 1200mAh ), para que funcione el modulo.  Pero No te preocupes, no es necesario alimentar solo con la batería el modulo, pues puedes conectar una fuente externa de 5V al conector micro USB, de tal forma que alimente al modulo y cargue la batería, y si por alguna razón se pierde la energía de la fuente externa, pues entra la batería automáticamente como respaldo. De esta forma, puedes usar una fuente externa y la batería queda como respaldo.  Pero si es necesario tener una batería conectada.   *Puedes encontrar aqui baterias lipo.

* El Modulo NO incluye la batería LiPo ni SIM.

* Incluye:

    Adafruit Fona 808 Breakout.
    Slim Sticker-type GSM/Cellular Quad-Band Antenna – 3dBi uFL.
    Passive GPS Antenna uFL – 9mm x 9mm -2dBi gain.
