The Arduino Fio is a microcontroller board based on the ATmega328P 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 or 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.
Operating Voltage: 3.3V
Input Voltage: 3.35~12V
Input Voltage for Charge: 3.7~7V
Digital I/O Pins: 14 (of which 6 provide PWM output)
Analog Input Pins: 8
DC Current per I/O Pin: 40mA
Flash Memory: 32KB (of which 2 KB used by bootloader)
Clock Speed: 8MHz

I'm not using this with an xBee but a WiFLY board from Roving Networks which gives you full Wi-Fi connectivity.
The board appears identical to the reference design, soldering of the headers and xBee socket is rather poor but nothing that can't be fixed with an iron.
Lots of sticky flux residue on the board but again cleaned in a minute.
it will charge the 1S LiPo anywhere from 3-6v input and a red LED indicates charging, turning off when finished.
If you wish to program this while the WiFLy is connected you will have to do two things.
1. send the command "set sys trigger 0x20" to the module followed by "save"
2. solder a switch between pin 4 of the xBee socked and 3.3v.
When the switch is closed it will put the module into sleep mode and you can program your arduino freely!
When ready to run again set the switch back to off.
Note: if you intend to use hardware debuging with a dragon or jtag-ice you will not need to remove C3 as you would on a Arduino Uno, just unplug the ftdi from the port.
Phew, that was a rambling diatribe!
Very good board, very good price, a few soldering issues.
