The Fio v3 is a new spin on the Arduino Fio hardware powered by the ATmega32U4.Not only is it small and LiPo-ready, it’s a very capable XBee-ready development board.
The JST-connector and 3.3v system voltage make this a great development tool for portable devices, simply plug in a Li-Poly battery and you’re ready to go. Wireless sensor networks and communication are made easy by the on-board XBee socket.
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 to actually program the device! Because this board uses a similar bootloader to the one on the Pro Micro, you will need to download and install the special software driver below. There’s also a board definition add-on for the Arduino IDE which will add support for this board.
We’ve updated this to the latest version of the 32U4 firmware, see the firmware note in the documents below!
Note: See the GitHub link below for support with the Arduino IDE.

Jargon buster
Plain-language definitions for the technical terms used above.
- Bootloader
- Small starter software on a microcontroller that lets new code be uploaded before the main program runs. Knowing how to enter bootloader mode matters when you need to program the board or recover it after a faulty sketch.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- LiPo
- A LiPo (lithium polymer) battery is a rechargeable lithium battery widely used in portable projects because it is light and compact. LiPo cells need correct charging circuitry and careful handling to stay safe, so equipment that supports LiPo generally includes charging or protection hardware suited to that battery type.
