Arduino Uno Mini Limited Edition

In celebration of the most popular Arduino board, the Uno, Arduino has made an Arduino Uno Mini! Featuring similar specs to the full-sized Uno and based on the ATMega328 microcontroller, this board is just as capable and is a neat memento for those of us who love the board or brand.

In addition to the classic microcontroller, the board features 14 digital pins and six analog, just like the full sized Uno. It uses 5V logic and has six PWM pins, too! The big difference besides size is the use of a USB Type C Connector instead of the classic USB-B.

Each item is unique and numbered on the PCB, and includes a hand-signed letter from the founders. It is a limited run, so we will not have additional stock after it has sold out!

Note: Due to expected demand and its limited nature, there is a limit of two boards per customer for the Arduino Uno Mini Limited Edition.

  • Microcontroller: ATmega328P
  • USB connector: USB-C
  • Built-in LED Pin: 13
  • Digital I/O Pins: 14
  • Analog input pins: 6
  • PWM pins: 6
  • UART, I2C, SPI
  • Circuit operating voltage: 5V
  • Input voltage (limit): 6-12V
  • DC Current per I/O Pin: 20 mA
  • DC Current for 3.3V Pin: 50 mA
  • Main Processor: ATmega328P 16 MHz
  • USB-Serial Processor: ATmega16U2 16 MHz
  • Memory ATmega328P: 2KB SRAM, 32KB FLASH, 1KB EEPROM
  • Weight: 8.05 g
  • Width: 26.70 mm
  • Length: 34.20 mm

Arduino Uno Mini Limited Edition Product Help and Resources

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.
See all skill levels

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Cute little Uno remake

This thing is actually quite a bit smaller than I though it was. I thought it was going to be the same size at the original Uno, but it’s about 1/3 to 1/2 the size. I don’t actually mind that. I think it looks pretty cute, actually. It functions exactly as the original Uno as far as I can tell so far. I haven’t extensively tested it yet, but so far it works great!

It's beautiful. I framed this. No idea if this microcontroller even functions.

The form factor is simply inspiring, and I look forward to soldering one of these guys (or a knockoff with the same footprint) straight onto another PCB via the castellated pins.

Awesome little Arduino

It Allows me to solder directly onto a circuit board and at the same time you can use header pins and have a perfect little mini-Arduino that you can use for prototyping. Microsoft is successful because no matter what platform you use you always get the same API. It is a consistent uniform API and if it changes it changes across all platforms uniformly. Arduino has hit a winner in the same sense that you have this tiny little Arduino, but you can recognize the same features and the same feel. You don't feel undue stress of having to go look-up pinouts and pdf manuals and re-learn the position of the pins and the reset button etc. That is a big plus for me. There's a sense of continuity with no learning curve

The big letdown or con: I didn't realize this but when I opened the box there were no header pins. Because the mini-Arduino resembles the bigger Arduino Uno when I purchased this little guy for whatever reason I assumed wrongly that I can use my regular pin headers. Imagine my surprise when I realized I can't use my regular headers. When introducing such a product you should have included headers at least initially. Or at the very least show them separately. Or as I have seen you guys do, put a requires section that one can click on to add headers. If I am wrong and you have the headers, I apologize. The missing headers is why I give it 4 stars otherwise it would have been a 5 star.

It's a beautiful little gem and I look forward to buying more.
