Qduino Mini: Arduino Compatible + Battery Charger & Monitor
Reserve yours today to be able to buy more later on SparkFun.com!
The Qduino Mini is perfect to embed in your electronics projects, it's super small, inexpensive, has a battery connector & charger built-in, & a fuel gauge that can tell you when to charge the battery!

Tell me more:
The Qduino Mini is Arduino-compatible & 100% open source, hardware and software meaning that making and programming your first circuit is a breeze. Hardware is hard, so we decided to make it a little bit easier. The day that the first Qduino Mini ships, all of the design files, including EAGLE board files, schematic, and code will be released under an open source license. Here's what it includes:
- Battery Charger Circuit - just plug in USB and it charges the battery with the auto switching circuit - there's no extra charger needed & no digging the battery out of your project so you can charge & program at the same time over USB!
- Battery Fuel Gauge - guessing on when your project runs out of juice? We've got you covered - we have a simple monitor library for your battery so you can remind yourself when it needs a little extra juice.
- Ultra small, Ultra thin, Ultra light - The Qduino Mini itself is 1in x 1.5in (2.6cm x 3.9cm) & 0.18oz (5 grams), perfect for quadcopters, drones or high altitude balloon projects. Both the Qduino Mini and the batteries (LiPos) used to power the board fit are super compact & thin, just right for embedding in your projects.
What can you make with the Qduino Mini?
- ATmega32U4 Processor - Arduino Leonardo Compatible
- 32KB Flash Storage
- 2.5KB SRAM
- 1KB EEPROM
- 3.3V @ 8MHz
- 20 Digital I/O // 14 Dedicated
- 12 Analog Channels // 6 Dedicated
- 7 Digital I/O also PWM channels
- SPI, I2C, UART available
- LED Indicators for: ON, Charge Status, TX, RX, D13
- TPS78233 3.3V 150mA Regulator
- MCP73832 LiPo Battery Charger
- MAX17048 LiPo Battery Fuel Gauge
Power Your Project:
LiPos are rechargeable, super thin, and extremely light, and are based on the Polymer Lithium Ion chemistry. You'll never have to take the LiPo out of your project - just plug in USB power to charge the battery. The LiPo's run at 3.7V, safe for any application. No more wasting AA batteries - these LiPos are rated for hundreds of uses.
The charging time for the LiPo's is around 1 - 2 hours, depending on how large the battery is.
How are prototypes going?
- 15+ fully functional Qduino Minis
- Arduino Sketches loaded over USB
- All I/O Pins & Analog Pins Tested
- UART, I2C, SPI functional
- Charging Circuit working with 3.7V LiPo Batteries
- Battery Fuel Gauge successfully reading LiPo Battery %
We are now working on perfecting the fuel gauge, more testing, and creating the online tutorials and firmware.
We are super excited to be teaming up with SparkFun Electronics, our sole manufacturer for this Kickstarter campaign. They will manufacture, program, & test the boards and fulfill the backer rewards. They have fulfilled over 11,000 MaKey MaKey Kickstarter Rewards and almost 7,000 MicroView Backer Rewards on time.
Nathan Seidle (CEO of SparkFun Electronics) has been a great mentor to me and has helped me engineer the Qduino Mini for the past year. I've known SparkFun for more than 3 years & they are awesome people to work with - they are ready to produce the Qduino Mini. They also proudly support Open Source Hardware. The bulk of SparkFun's products are environmentally safe & RoHS compliant.
The Qduino Mini's parts will be sourced from the USA and China, but all will be manufactured at SparkFun HQ in the USA.
The Qduino Mini will be shipped from SparkFun in the USA (Niwot, Colorado). Shipping anywhere in the USA is an additional $5 per pledge.
- All shipping methods (domestic and international) are tracked -
International shipping is an additional $24 per pledge. We ship internationally to most countries, and all international customers are responsible for import fees. We cannot ship to: Iran, Cuba, North Korea, Sudan, Syria, Brazil, and Russia.
Note: LiPos are not included because of shipping restrictions in any reward level, except for the Qtechknow Creator Kit.
Note: Headers are not included in any of the reward levels, except for the Qtechknow Creator Kit (which has female headers soldered on to allow quicker learning).
Here's our proposed timeline:
What will we do with the money?
The $12,500 of funds from the Kickstarter will help us:
- Kickstart our project of Qduino Mini's & keep the project going
- Order all of the parts in bulk from the USA and China, to get the costs down
- Make the current prototype perfect for production
- Safety testing for the charger circuit and battery monitor
- Online tutorials to get started with the Qduino Mini
Quin Etnyre of Qtechknow discovered electronics by reading Make Magazine and attending his first Maker Faire Bay Area in 2011. He has taught himself Arduino, taken classes and has had excellent engineering, business, and design mentors including Nathan Seidle and Jeff Branson of Sparkfun, Bob Martin of Atmel, and Diego Porqueras of Deezmaker 3D Printers and Hackerspace. He started his own business, Qtechknow in 2012, which features ArduSensors, a line of fun and educational kits that he developed to empower anyone to experiment with electronics, regardless of age, background or skill level. He strongly believes in the power of open source hardware, and all his projects are open source. He teaches adults and kids in his “Intro to Arduino” classes, has 28 Instructables published with 470,000+ views, maintains his own website and store at Qtechknow.com, was featured in Popular Science, Make Magazine, & the BBC and has presented his projects at Maker Faires around the world including the White House Maker Faire in 2014. He is 14.

Risks and challenges
One of the most common challenges in hardware Kickstarter campaigns is manufacturing. Our component manufacturers, PCB manufacturers, and assemblers all are in the US, or China. SparkFun Electronics, our sole manufacturer, has over 10 years of experience in engineering, manufacturing, and order fulfillment.
Although I am 14, I have the full backing of my parents. My PCBs and development boards have been reviewed by expert engineers from SparkFun Electronics. All Qduino Minis have been tested over and over, and are all safe & high quality products.Learn about accountability on Kickstarter
