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
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)
