The Breaduino is a Arduino in a bare-bones factor. The Breaduino includes the pin 13, communication, and power LEDs as well as an ATmega328p, a LiPo connector, and a reset button. This makes a great soldering kit.

When you connect this to the Arduino IDE, make sure to select the Arduino UNO in the boards menu.

Note: This does not have a voltage regulator in the kit, so do not connect more than 5V.


The Breaduino comes as a kit that you solder at home.

What is Qtechknow?

Qtechknow was founded in 2012 by eleven year old, Quin Etnyre. The kits and products, all designed by Quin, have enabled people of all backgrounds have success in electronics - beginners to experts, seven year olds to retired professors. Our product lines have included soldering kits, breakout boards, and development boards. Our most popular design has been the Qduino Mini, successfully Kickstarted in 2015. It is a tiny, Arduino-compatible board with the unique features of a fuel gauge, built-in charger, and a battery connector. It was one of the only development boards designed by a kid, and also one of the few embedded boards delivered on time on Kickstarter!

Quin recently started at UC Berkeley, and is focusing on studying and has narrowed his business focus to the Qduino Mini. Please see the link to Sparkfun to purchase one now! Our other products have been retired, but we will continue to have all the data on this website for your reference.

Thanks for all of your incredible support for the past six years, and keep an eye out for Qtechknow in the future!
