Description
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.
- Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested)
- 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
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 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
