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 powerfull GSM
cellular module (we use the latest SIM808 V2) 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 (MT3336 chipset) that can be controlled and
query over the same serial port
* Make and receive voice calls using a headset or an external 32
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 32 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
* 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!
* SIM Card! A 2G Mini SIM card is required to do anything on the
* Lipoly Battery - 500mAh or larger!
* MicroUSB cable for charging the battery.
* External uFL GSM Antenna
* External uFL Passive GPS Antenna
There's also some recommended accessories. They are not required but
chances are you'll want them!
* TRRS 4-Pole Headset - Any 'iPhone' or 'Android' compatible (but
not iPhone original) should work. We tried about 10 different ones,
and basically the more expensive once are more comfortable and louder
but our official iPhone headset mic did not work.
* Vibrating motor - the FONA can drive this directly, just solder a
mini vibrating motor disc in!
* USB console cable - the microUSB connector is for charging only,
but you can wire up a console cable for direct-connection to the
module if you want to send commands from a terminal (great for testing
