The Arduino Fio is a microcontroller board based on the ATmega328V runs at 3.3V and 8 MHz. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, an on-board resonator, a reset button, and holes for mounting pin headers. It has connections for a Lithium Polymer battery and includes a charge circuit over USB. An XBee socket is available on the bottom of the board.
The Arduino Fio is intended for wireless applications. The user can upload sketches with an a FTDI cable, Arduino ISP, or Sparkfun breakout board. Additionally, by using a modified USB-to-XBee adaptor such as XBee Explorer USB, the user can upload sketches wirelessly. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires.
The Arduino Fio was designed by Shigeru Kobayashi and SparkFun Electronics, and manufactured by SparkFun Electronics.
