Arduino Adafruit Feather 32u4 FONA GSM

Feather es la nueva gama de Arduinos compactos fabricados por “Adafruit Industries”, compatibles al 100% con el software de Arduino.  Estos arduinos tienen la característica de contar con un conector para baterías lipo (puedes cargarla desde el micro usb), ademas de que cada Feather cuenta con algún periférico especial (GSM, Wifi, Bluetooth, microSD, …)

Este Feather Fona incluye un microcontrolador ATmega32u4 (como si fuera un Arduino Leonardo) y un Modulo Celular GSM/GPRS SIM800 !  Ideal para controlar o monitorear tu Arduino a distancia por la red movil celular.  Solo inserta tu tarjeta SIM de cualquier compañía celular y listo !!

Feather is the new development board from Adafruit, and like its namesake it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.

This is the Adafruit Feather 32u4 FONA – our take on an ‘all-in-one’ Arduino-compatible + audio/sms/data capable cellular with built in USB and battery charging. Its an Adafruit Feather 32u4 with a FONA800 module, ready to rock!

At the Feather 32u4’s heart is at ATmega32u4 clocked at 8 MHz and at 3.3V logic, a chip setup we’ve had tons of experience with as it’s the same as the Flora. This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program & debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc.

Since you’ll be taking this on the road, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. A 500mAh+ Lipoly battery is required for use, it keeps the cellular module happy during the high current spikes. Plug the Feather into microUSB to charge at 500mA.

Here’s some handy specs! Like all Feather 32u4’s you get:

    * Measures 2.4″ x 0.9″ x 0.28″ (61mm x 23mm x 7mm) without headers soldered in.
    * Light as a (large?) feather – 8.2 grams.
    * ATmega32u4 @ 8MHz with 3.3V logic/power.
    * 3.3V regulator with 500mA peak current output.
    * USB native support, comes with USB bootloader and serial port debugging.
    * You also get tons of pins – 20 GPIO pins.
    * Hardware Serial, hardware I2C, hardware SPI support.
    * 8 x PWM pins.
    * 10 x analog inputs.
    * Built in 500mA lipoly charger with charging status indicator LED.
    * Pin #13 red LED for general purpose blinking.
    * Power/enable pin for the 3.3V regulator
    * 4 mounting holes
    * Reset button

Connect your Feather to the Internet or make phone calls with our trusted-and-tested FONA module. 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. 

    * 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 an external 8? 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)
    * AT command interface with «auto baud» detection.
    * Pair-able Bluetooth client interface with SPP (for controlling the module) as well as audio.


* Para usar el modulo GSM SIM800 sin problemas, es necesario conectar una batería lipo de al menos 500mAh, pues al momento de transmisión se producen picos altos de consumo de corriente que la batería puede suministrar sin problemas.  Aquí puedes encontrar baterías lipo.

* NOTA:  NO incluye batería Lipo.    


* Incluye Antena “Slim Sticker-type GSM/Cellular Quad-Band Antenna – 3dBi uFL”.
