Description

The Feather is the new development card developed by Adafruit and as its name suggests, Feather pen in English means, it's small, light and can you raise! It was designed to establish a new standard of small microcontroller.

This version of the map Feather has a module FONA800 to add the feature Audio/SMS and GPRS DATA with a management integrated with a micro-USB connector battery charge.

It is composed of a heart to the ATmega32u4 clocked at 8 MHz controller database. This circuit has 32KB of Flash and 2KB of RAM and a built-in USB epile which allows to program USB directly and even emulate a keyboard, a mouse, or even a MIDI enables.

In order to realize mobile montages, this card has of a built-in connector JST dedicated battery Lithium polymer 3, 7V with a charging circuit minimum 500mAh for this Feather card. If you do not need battery, simply feed it through the micro-USB with a source delivering 500mA connector. The Feather card will automatically switch between USB power and the battery if needed. 

Opportunity through the FONA800 module:

• Quad-band 850/900/1800/1900 MHz: connection to any GSm 2 G network
• Make and receive call year using an external speaker 8 ohms and an electret microphone
• Sending and send SMS
• GPRS connection (TCP/IP, HTTP, etc.)
• Scan and the FM radio recption
• AT commands with auto-detction of baud
