The Adafruit FONA 800 Cellular GSM Voice and Data Shield for Arduino could put your next project in touch with the world. Send and receive SMS messages and GPRS data, make and answer phone calls, and listen to FM radio. In fact enough functions to build a working phone, including driving a vibration motor and recharging a LiPo battery from the USB power. The board needs a microcontroller to drive it and will work with anything that can send and receive serial data, from an Arduino to a Raspberry Pi. The example wiring uses only 4 x microcontroller pins, though you can probably get by with just Tx/Rx. Adafruit have a free FONA tutorial which demonstrates how to wire them up and interact with them using the AT command set from a serial terminal. While you're developing your application you can use a serial terminal to send commands and get responses so that you can see exactly what's happening.
Supplied as a fully assembled board plus a strip of 0.1in. male header pins for you to solder on as required. You will also need a microcontroller with a serial UART (3 to 5V compliant), a 2G mini SIM card (15 x 25mm) to connect to a mobile network, a 500mA+ LiPo battery, a micro-USB cable to charge the battery and an external antenna with a uFL connector.
- Use mobile voice, text, SMS and data in your next project
- uFL connector for external antenna
- Add a TRRS headset or speaker & electret mic for voice calls
- AT serial command interface
- 3 to 5V power and logic compatible
- Adafruit part no.: 2468
