The UNO Mini Limited Edition is a return of the popular Arduino board. Pre-orders have just opened, so don't wait if you want to own a piece of Arduino history.
The UNO Mini Limited Edition is here to meet you.
First and foremost, this is a standard UNO. It has (nearly) the identical specifications as the UNO, including the same CPU, pinouts, and performance. However, there are a handful of nice changes that we hope you'll enjoy.

The USB port has been upgraded to USB-C, which is probably one of the first things you noticed. We're convinced you'll like this upgrade, and it's not only because it helps with the smaller form factor. It's a lot more handy because most of us have a lot of spare USB-C cables lying around these days.
Then there's the matter of the form factor. The UNO Rev 3 is around the same size as its predecessors, indicating that it is a reincarnation of the original design. The UNO Mini Limited Edition, as expected, is a fourth of the size of the original, measuring 34.2mm x 26.7mm x 8mm.
Technical Specifications
The ATmega328P-based Arduino UNO Mini LE is a microcontroller board (datasheet). Six analogue inputs, a 16MHz ceramic resonator, a USB-C connection, and a reset button are among the 14 digital inputs/outputs (six of which may be utilised as PWM outputs). This package includes everything you'll need to get started with the microcontroller. To get started, just connect it to a computer by USB, utilise a power adapter, or attach a battery.
