Build your own cellular project and get off the grid with FONA. This pack comes with an SMA-antenna type FONA and paired with hand-picked accessories. It's the Adafruit FONA - SMA Starter Pack.
The FONA miniGSM is 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 starter pack has an SMA connector.
- Quad-band 850/900/1800/1900MHz - connect onto any global GSM network with any 2G SIM (Note that not all countries have working 2G networks, there is no USA 2G network anymore)
- 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 its charging and done
- Standard 4-pole TRRS headphone jack. Use any 'Android' or 'iPhone'-compatible headset with 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
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.
Microcontroller not included! We recommend an Arduino UNO to go along SIM card not included!
