Arduino Funnel I/O (FIO) Board with ATmega32U4 microcontroller, XBee Socket and LiPoly Charger Circuit

The FIO v3 is a new spin on the Arduino FIO hardware. Instead of an ATmega328V, the FIO v3 features an ATmega32U4 processor. This makes it possible to program the FIO via USB bootloader. It also uses a micro-USB connector instead of mini-USB.

The JST connector and 3.3V system voltage make this a great development tool for portable devices. Simply plug in any of these Polymer Lithium Ion batteries and you're ready to go. Wireless sensor networks and communication are made easy by the on-board XBee socket, into which you can plug any of these XBee modules.

The ATmega32U4, running at 8MHz, makes it possible for you to use the on-board USB jack not only to charge a connected Li-Poly battery, but also to program the device.

Because this board uses a similar bootloader to the one on the Arduino Pro Micro, you will need to download and install a special software driver (see below).
