The revolutionary UNO R4, introduced on Arduino Day, is now obtainable on the Arduino Retailer!

The fourth model of the long-lasting, beloved UNO provides a complete new dimension to the world of DIY and making revolutionized by the straightforward 8-bit microcontroller over a decade in the past. Take your maker potential to new heights: UNO R4 has a speedy 32-bit Arm® Cortex®-M4 and affords a 16-fold improve in reminiscence, in addition to extra connectors and connectivity choices than ever – in two variants: UNO R4 Minima and UNO R4 WiFi. 

What’s within the new UNO?

Each variants let you begin making or simply improve UNO R3-based initiatives with extra computational energy, reminiscence, and pace than earlier variations – courtesy of the RA4M1 microcontroller by Renesas – whereas sustaining the identical kind issue and 5V working voltage. 

• Extra reminiscence and sooner clock: A 16x improve in reminiscence and 3x the clock pace imply the UNO R4 can carry out extra exact calculations and deal with extra advanced and complicated initiatives than ever.
• New built-in peripherals: Amongst a number of thrilling new peripherals, you get a 12-bit DAC, CAN BUS, OP AMP, and SWD port – every one increasing your maker potential, permitting you to simply deal with more and more superior initiatives.
• A USB-C® Connector: Embracing the smaller, extra highly effective, and strong cable commonplace!
• An HID system: This function makes interactive initiatives one million instances cooler, permitting you to create interfaces with minimal effort and very quickly.

You will get began in your subsequent automation or audio mission with the UNO R4 Minima – a high choose for first-time makers, with its mixture of highly effective know-how and reasonably priced value – or you possibly can go for the UNO R4 WiFi in case you want extra particular options.

Connect with your inside creativity with the UNO R4 WiFi

The UNO R4 WiFi variant is ideal for all customers, from newbies to consultants, eager to discover the forefront of innovation. This full-fledged board options an ESP32-S3 coprocessor that handles Wi-Fi^® and Bluetooth^® Low Vitality connectivity, so the RA4M1 microcontroller can concentrate on different duties. On high of all of the options within the Minima variant, it affords:

• Wi-Fi® and Bluetooth® connectivity, plus Cloud-compatibility: construct IoT initiatives, create interactive dashboard and management your mission remotely.
• A 12×8 LED matrix: think about engaged on a inventive mission utilizing animations or plotting sensor knowledge, with none extra {hardware}!
• A Qwiic connector to facilitate fast prototyping: because of all kinds of suitable modules that may be related over I2C, you possibly can simply create customized initiatives and broaden the capabilities of your UNO R4 WiFi.
• A built-in mechanism that detects operations that may trigger a crash: if it catches errors reminiscent of a division by zero, the board stops them earlier than they will trigger hassle and offers an in depth rationalization on the serial monitor

“The Arduino ecosystem has developed, during the last 20 years, because of the highly effective thought of open supply and the stellar neighborhood of 30+ million makers who hold sharing, constructing, and enhancing. Each new {hardware} product, each new software program answer has added new worlds – able to welcome everybody. Now, the UNO R4 takes the ecosystem and the neighborhood to a brand new dimension of efficiency.”

– Massimo Banzi, Arduino co-founder

So, in case you’re simply starting your Arduino journey, the discharge of the UNO R4 makes it a good time to begin!

Already an UNO fan? The UNO R4 makes it straightforward to port present shields and initiatives to a complete new stage, and chosen contributors are already serving to us replace UNO R3 libraries. 

A last massive thanks goes to our neighborhood and early adopters, who’ve supported us these previous few months by contributing their efforts to porting libraries.

What are you ready for?
