Adafruit FONA - Mini Cellular GSM Breakout uFL Version

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. This version has a uFL connector. For the SMA version, click here!

Sounds delicious, right? So we plated this fine module onto a little breakout with all the extras you need to make your next project shine:

On its own, this module can't do anything. It requires a microcontroller to drive it! We suggest and use an Arduino but any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.

You will also need some required accessories to make FONA work. These are not included!

There's also some recommended accessories. They are not required but chances are you'll want them!

Technical details

• Dimensions w/Components: 45mm x 34mm x 8mm / 1.8" x 1.3" x 0.3"
• Dimensions of PCB: 45mm x 32mm x 2mm / 1.8" x 1.3" x .1"
• Weight: 9.0g

Revision History:

• As of December 22, 2015 we have replaced the SIM800L module with SIM800H which is backward compatible. Note that this board design does not have a bluetooth antenna on it so you cannot use the BT capabilities of the SIM800H
• As of December 27, 2016 we are selling a new firmware revision of the module. The library is backwards compatible but we notice that the speaker output is a little quieter.
