Key Features:

• 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 32ohm speaker + electret microphone
• Onboard LiPoly battery charging circuitry so you can take your project on the go.
• Vibrational motor (buzzer) driver so you can have noiseless notifications
• Indicator LEDs for power and network connectivity

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. (It does not contain a drum machine, tho)

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.
