Overview

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 measure only 1.75"x1.6" but packs a surprising amount of technology into it's little frame. At the heart is a powerfull 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 (in the USA, T-Mobile is suggested)
  • Fully-integrated GPS (MT3336 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: 30s (typ.)
    Hot starts: 1s (typ.)
    Warm starts: 28s (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 but any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.

You will also need some required accessories to make FONA work. These are not included!

There's also some recommended accessories. They are not required but chances are you'll want them!
