Introducing the Arduino UNO Mini Limited Edition
Arduino has expanded their product line with a new and exciting addition: the Arduino UNO Mini Limited Edition. This is an updated and compact version of the original Arduino UNO, which has been around for a number of years. The board itself measures just 26.7 x 34.2 mm, making it perfect for projects on the go or in tight spaces where you need to conserve space.
What is the Arduino UNO Mini Limited Edition?
As with any Arduino, this one comes loaded with features and abilities. It has 14 digital input/output pins (of which six can be used as PWM outputs) and 6 analog inputs. You’ll also find a 16 MHz crystal oscillator along with an IC socket for adding your own ATmega328 microcontroller chip so you can easily swap out the included UNO bootloader for your own. The board also comes with a USB connection, so you can get started building right away. And since this is an Arduino product, getting up and running couldn’t be easier. If you have experience using other Arduino boards then things should feel very familiar to you.
Who is the Arduino UNO Mini Limited Edition for?
This is a perfect entry-level board for students or beginners, and it’s equally good for advanced users who want to make use of the tiny footprint. It comes with all supporting hardware you need including a USB cable, jumper wires, and headers so that you can get started with your project right away!
The Arduino UNO Mini Limited Edition is a great option for anyone looking to save some space in their projects. Not only does it come with the same compatibility as other Arduinos, but it comes at an affordable price too! Overall this product release by Arduino has been received very well so far, especially since they are known for making products that are easy to use and the Arduino UNO Mini Limited Edition is no exception!

Final thoughts
The UNO Mini Limited Edition is available for pre-order right now here on the Arduino Store and will be available on the Electromaker Shop very soon. We think this board will be a hit with seasoned Arduino lovers and also new makers who want to get to grips with hobbyist electronics. The team here at Electromaker is looking forward to getting our hands on a test unit soon! Stay tuned for a full review over the next few weeks.
