Description: 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.

This is a nice board, easy to use and convenient to experiment with due to the USB loader.
Unfortunately, little thought was put into lowering the power consumption, so battery drain is far worse that it could/should be.
I don’t feel like replacing SMT resistors, so that battery sensor alone drains the battery. Add all the bright LEDs and the board is disappointing.
I also had issues reloading the official bootloader.
I can successfully upload code to the board but the Serial communication does not appear to work. I have worked with many Arduino based boards since v1 or their IDE so I am familiar with how to set the baud rate for both the board and the monitor. I tried different rates too just in case some were not supported ( for whatever reason ). Would love to know if I was just missing something.
UPDATE: Looks like this board uses Serial in a different way, so make sure to read up on Serial1 vs Serial usage as they suggested. Board works as expected using Serial1.
Thanks for your feedback. Because the ATmega32U4 has built in USB, the USB serial line is different than the hardware serial line. For the hardware serial line make sure to use Serial1. If you still have any questions feel free to email email@example.com and they should be able to help you out.
