Adafruit FONA 808 - Mini Cellular GSM + GPS Breakout

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.Item SpecificsQuad-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 anymore)Fully-integrated GPS (MT3337 chipset with -165 dBm tracking sensitivity) that can be controlled and query over the same serial portMake and receive voice calls using a headset or an external 32Ω speaker + electret microphoneSend and receive SMS messagesSend and receive GPRS data (TCP/IP, HTTP, etc.)PWM/Buzzer vibrational motor controlAT command interface with "auto baud" detectionStandard SIM slides into the backGPS Specifics22 tracking / 66 acquisition channelsGPS L1 C/A codeSensitivity: Tracking: -165 dBm, Cold starts : -147 dBmTime-To-First-Fix: Cold starts: 32s (typ.), Hot starts: 1s (typ.), Warm starts: 5s (typ.)?Accuracy: approx 2.5 metersSize:44mm x 43mm x 8mm / 1.7" x 1.7" x 0.3"Weight: 12.3gRequires (not included) a microcontroller, SIM CARD, LiPoly Battery, Micro USB cable, uFL GSM Antenna, Passive GPS antenna.
