FONA SIM800 GSM Module Shield for Arduino
Introducing Adafruit FONA 800 Shield, an adorable all-in-one cellular phone shield that lets you add voice, text, SMS and data to your project in an easy to use pluggable shield. This shield fits on top of any classic Arduino or compatible and packs a surprising amount of technology into its little frame. At the heart is a GSM cellular module (we use the latest SIM800H) the size of a postage stamp. This module can do just about everything. On its own, this shield can't do anything. It requires a microcontroller like an Arduino to drive it! You will also need some required accessories to make FONA work. These are not included!
Features:
- Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (in the USA, T-Mobile is suggested)
- Make and receive voice calls using a headset OR an external 8Ω speaker + electret microphone
- Send and receive SMS messages
- Send and receive GPRS data (TCP/IP, HTTP, etc.)
- Scan and receive FM radio broadcasts (yeah, we don't exactly know why this was included but it works really well)
- PWM/Buzzer vibrational motor control
- AT command interface with "auto baud" detection
