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.
Please note: The T-Mobile GSM network is shutting down in the USA over the course of 2020 and beyond, so please be aware these are not for long term usage in the USA! Please check out the FONA 3G for next-generation usage.
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!
