Description: The Qduino Mini is a tiny, Arduino-compatible board with a battery connector and charger built-in as well as a fuel gauge that can tell you when to charge the battery! This little guy is super small, inexpensive, and is perfect to embed in your electronics projects. The Qduino Mini is the same model awarded to its Kickstarter backers and is Arduino-compatible and 100% open source, meaning that making and programming your first circuit is a breeze.
Here’s what the Qduino includes:
Additionally, each Qduino is also breadboard compatible and has two RGB LEDs. One for status and another that is user programmable!
Note: Please be sure to double check your board type before uploading to make sure you have “Qduino Mini” selected in the IDE. Otherwise, you could potentially brick your new Qduino board.
Note: A portion of each sale is given back to Quin Etnyre of Qtechknow for continued development into the world of electonics.

I wish I had this when I built my last battery powered Arduino project. The onboard battery charger/regulators are something that should be included with every Arduino (in my humble estimation). The battery level indicator is also critical - on my last project I had no way to show the batt level. Kudos. The only thing I would like to see, eventually, is a larger/faster Atmel processor. I made a quick video about this on my YouTube channel.

I have one and am trying to base a project around it, because the integrated battery charger is great – I can plug it in to charge a battery without worrying about swapping batteries.
However, the problem I’m running into relate to the pins they chose to use for the user controlled LED – I want to do audio using something like Mozzi, which can do high quality audio using PCM output on two pins on the same timer. By default, Mozzi uses 9 and 10, but 10, 11 and 12 are used by the LED. Most of the pairs of the timer pins that could be used for this seem to need one of these pins. Frustrating.
I’d be happy to do away with the LED to have more flexibility in how I use those pins!

One review is worried that this board is missing pins 10, 11, 13. They’re actually available (and disguised) on the board as the “MISO MOSI & SCK / D14, 15, 16” pins. These ARE pins 10, 11, 13 according to the designer. So this board is a complete Arduino board with the added bonus of an extra LED for status reports.
If you are looking for a Qduino-specific driver, it can be found here:
It is the /Software/qduinomini.tar file.
If you have a Qduino that is not being recognized by your computer and you are not able to upload new Arduino code, you might be able to recover the board using the double reset method. Try looking here for more information => [ https://learn.sparkfun.com/tutorials/pro-micro–fio-v3-hookup-guide#troubleshooting-and-faq ]. You can also try to look at the troubleshooting comment under
bboyho for the other ATmega32U4 development boards [ https://learn.sparkfun.com/tutorials/pro-micro–fio-v3-hookup-guide/discuss#comment-56aa5cabce395f9f2d8b456d ]. There is a list of detailed instructions on reviving each of the other SparkFun ATmega32U4 development boards under the tech tips. Just make sure to select the “Qduino Mini” board when recovering the board.
We had a case where a customer’s Qduino was not able to be recognized on their Windows computer. By following the double reset method and uploading Arduino code when the board was in bootloader mode, they were able to recover the Qduino.
