Adafruit FONA - Mini Cellular GSM Breakout - SMA Version

Ring, Ring! It's your breadboard calling with the Adafruit FONA MiniGSM, a compact all-in-one cellular phone module. This tiny powerhouse, measuring only 1.75"x1.25", integrates voice, SMS, and data capabilities into your projects.

Equipped with the latest SIM800 GSM module, this device operates on quad-band 850/900/1800/1900MHz frequencies, ensuring global GSM network compatibility with 2G SIMs where available. Voice calls can be made using a headset or an external speaker and microphone setup. It also supports SMS messaging and GPRS data operations.

A unique feature is its ability to scan FM radio broadcasts, offering versatile usage. It includes onboard LiPoly battery charging circuitry for mobility, a TRRS headphone jack for convenient headset connections, and an SMA connector for external antennas. Integrated LEDs indicate charging and network status.

Though designed for experienced users, the FONA module requires a compatible microcontroller like an Arduino to drive operations, offering seamless integration with 2.8V to 5V logic systems via level-shifting circuitry. Enhance project possibilities further with accessories like a vibrating motor driver, external mic and speaker, and USB console cable for direct command input.
