Adafruit FONA 808 - Mini Cellular GSM + GPS Breakout [Discontinued]

Adafruit FONA 808 MiniGSM + GPS adds cellular voice, SMS, data and GPS tracking in one tiny module (1.75" × 1.6") using the SIM808. Note: T-Mobile GSM shutdown makes it unsuitable for long-term use in the USA—consider FONA 3G instead.

Want cellular + GPS tracking in one module? The Adafruit FONA 808 MiniGSM + GPS combines a Mini GSM phone module with integrated GPS, letting you add location tracking, voice calls, text, SMS and data to your project in a compact package. Measuring just 1.75" × 1.6", it packs in a SIM808 GSM cellular module with built-in GPS, giving you a flexible all-in-one solution for connected projects. Important note (USA): the T-Mobile GSM network has been shutting down in the USA from 2020 onwards, so this module isn’t suitable for long-term use in the USA. For a more future-proof option, Adafruit recommends the FONA 3G instead.

Features

* Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (Note that not all countries have working 2G networks, there is no USA 2G network any more)

* 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’ve mounted this handy module onto a breakout board and added the extra features you need to get up and running quickly, and 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 won’t do anything — it needs a microcontroller to control it. We recommend using an Arduino, but any 3–5V microcontroller with a UART can communicate by sending and receiving commands over the RX/TX pins. You’ll also need a few required accessories to get the FONA working. These are not included.

* SIM card (required)

* LiPo battery (500mAh or larger) (required)

* A 500mAh battery works well

* A 1200mAh battery also works great

* Micro USB cable for charging the battery

* External uFL GSM antenna (required)

* A slim uFL antenna works well - If you want to use an SMA antenna, you’ll also need a uFL to SMA adapter cable

* External uFL passive GPS antenna (required)

Specifications

* 44mm x 43mm x 8mm

* Weight: 12.3g

Revision History

* As of Dec 11, 2015 we are shipping with the version 2 SIM808 module which has a slightly different GPS command naming system (AT+CGNS rather than AT+CGPS), and a newer GPS chipset (MT3337 not MT3336)
