Qduino Mini: Arduino Compatible + Battery Charger & Monitor

About this project

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!

Qduino Mini

The Qduino Mini is Arduino-compatible & 100% open source, hardware and softwareΒ meaning that making and programming your first circuit is a breeze. Β Hardware is hard, so we decided to make it a little bit easier. Β 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. Β 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? Β 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. Β 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.
  • ATmega32U4 Processor – Arduino Leonardo Compatible
  • 32KB Flash Storage
  • 2.5KB SRAM
  • 3.3V @ 8MHz
