Adafruit Feather 32u4 FONA

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!  We have other boards and accessories in the Feather family, check'em out here.

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
