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 an SMA connector. For the uFL 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
Cellular modules can be a bit challenging to use, the FONA is intended for hackers and advanced makers. We're still adding library support for all the various things the FONA can do but there may be updates as FONA is used around the world!
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!
January 4, 2016 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
August 25, 2016 the SIM800 module has been updated to S2-1065N-Z142K parts (firmware version B07)
