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!
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
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
Onboard LiPoly battery charging circuitry so you can take your project on the go. Use any 500mAh+ LiPoly or LiIon battery and recharge over the MicroUSB when necessary. Two LEDs let you know when it is charging and done
Standard 4-pole TRRS headphone jack. Use any 'Android' or 'iPhone'-compatible headset with a mic
Breakouts for external 8Ω speaker and electret mic if you don't want to use a headphone
Level shifting circuitry so you can run it with 2.8V to 5V logic.
Vibrational motor (buzzer) driver so you can have noiseless notifications
SMA connection for external antenna
Indicator LEDs for power and network connectivity
Standard SIM slides into the back
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 using an Arduino but any 3-5V microcontroller with a UART can send and receive commands over the RX/TX pins.
Revision History:
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)
You will also need some required accessories to make FONA work. These are not included!
SIM Card!
Lipoly Battery - 500mAh or larger! This 500mAh battery, or this 1200mAh will work great.
There are also some recommended accessories. They are not required but chances are you'll want them!
TRRS 4-Pole Headset - Any 'iPhone' or 'Android' compatible (but not iPhone original) should work. We tried about 10 different ones, and basically, the more expensive ones are more comfortable and louder but our official iPhone headset mic did not work.
