Product Details


Welcome the latest additions to the ever-popular and trusted Arduino UNO family; the Arduino UNO R4 range. Building on the existing features of the UNO family that you know and love, the UNO R4 range benefits from a powerful 32-bit microcontroller and some incredible new features making them the perfect prototyping and learning tool for everybody! The Arduino UNO R4 comes in two variants, this is the UNO R4 Minima.


What makes the Arduino UNO R4 Minima awesome?

The Arduino UNO range is renowned for being a user-friendly, robust, and accessible platform, it’s levelled-up and sets a new standard for prototyping and learning tools with the UNO R4 Minima! Its 32-bit microprocessor offers more, memory, connectors, and connectivity options than previous generations, combine that with its affordable cost and you have the perfect tool for first-time makers.

A powerful device at an affordable price
UNO R4 Minima is a powerful device offering awesome performance at an affordable price, but that doesn’t mean it’s lacking in features, it’s all about making high-end tech affordable, and accessible for everybody!

Compatible with previous generations
It’s frustrating when a new generation of tech is released, and it is not compatible with the previous generations. The good news is that UNO R4 has the same pinout and 5V operating voltage as the UNO R3, so any existing shields or projects you’ve been working on can be easily ported to the UNO R4.

Awesome new features
Let’s talk about some of the awesome new features of the UNO R4. It features several incredible new peripherals, including a 12-bit DAC, CAN BUS, OP AMP, and SWD port. These additions open a realm of new possibilities for makers to create incredible solutions and advanced projects.

More memory, faster clock
With 16x more memory and a 3x faster clock, the UNO R4 Minima can perform precise calculations and handle complex projects with ease.

A robust device you can rely on
UNO R4 boards benefit from several protective features, including overcurrent protection on the pins of the RA4M1, and the circuit has been designed in a way to prevent wiring mistakes reducing the risk of damage to the board. It can be powered up to 24V depending on your needs.

Efficient debugging
The UNO R4 Minima features an on-board SWD port that provides a straight-forward and reliable way to debug any issues by simply connecting a third-party debugging probe.
