Ring, Ring! Who's that callin'? It's your breadboard! Introducing Adafruit FONA MiniGSM, an adorable all-in-one cellular phone module that lets you add voice, text, SMS and data to your project in an adorable little package.This module measures only 1.75"x1.25" but packs a surprising amount of technology into its little frame. At the heart is a GSM cellular module (we use the latest SIM800) the size of a postage stamp. 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) 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 Cellular modules can be a bit challenging to
