Arduino Fio



Product ID: 19713 SKU: Ard-19713 Categories: , Tags: ,

The Arduino Fio represents a microcontroller board that relies on the ATmega328P chip, operating at 3.3V and 8 MHz. It encompasses 14 pins that function as digital input/output, with 6 of them adaptable for PWM output use. Additionally, there are 8 analog inputs, an on-board resonator, a reset button, and holes meant for attaching pin headers. The board facilitates connection to a Lithium Polymer battery, featuring a USB-based charging circuit. Notably, the underside of the board accommodates an XBee socket.

Designed for wireless applications, the Arduino Fio permits users to upload sketches using an FTDI cable or a Sparkfun breakout board. Alternatively, through the utilization of a modified USB-to-XBee adapter like the XBee Explorer USB, sketches can be uploaded wirelessly. The board is sold without pre-mounted headers, thereby enabling the utilization of diverse connector types or direct wire soldering.


The FIO comes as a bare board. You need to attach pins, pin-headers, or other terminals to any inputs and outputs you wish to use. This is true for the FTDI pins (labelled on the underside), necessary for uploading programs to the FIO.

Key features of the Arduino Fio include:

  1. Wireless Connectivity: The Fio board has an integrated Xbee socket, which allows you to easily attach an Xbee module for wireless communication. Xbee modules are commonly used for creating wireless networks and connecting devices over longer distances.
  2. Li-Po Battery Connector: The Fio includes a connector for attaching a lithium polymer (Li-Po) battery. This makes it well-suited for portable and battery-operated projects.
  3. Voltage Regulator: The board has an onboard voltage regulator that can handle higher voltage power sources and provide a stable 3.3V output for powering the components.
  4. JST Connector: A JST connector is included on the board for charging the Li-Po battery and powering the board.
  5. Programmable: Like other Arduino boards, the Fio is programmable using the Arduino IDE, allowing you to write and upload code to control various components and perform different tasks.
  6. I/O Pins: The Fio board features a number of digital and analog input/output pins that you can use to connect sensors, actuators, and other electronic components.
  7. Compact Size: The Fio is designed to be small and lightweight, making it suitable for wearable technology and projects that require a compact form factor.

The Arduino Fio was especially popular for projects involving remote sensing, data collection, and wireless communication.
