Arduino UNO R4 is a big leap ahead for an open supply group of tens of millions

The historical past of creating is now prepared for the long run: a 32-bit UNO will quickly be out there due to a robust Renesas processor

Right here at Arduino we’re thrilled to announce a brand new, revolutionary revision of the long-lasting UNO board, which is able to develop the idea of the open-source model’s most iconic and in style product whereas offering the maker group with a long-awaited replace on efficiency and potentialities. The Arduino UNO R4 certainly preserves the well-known options of the UNO household – commonplace kind issue, defend compatibility, 5V working voltage, excellent robustness – whereas providing a minimum of a 32-bit Cortex^®-M4 and a 3-to-16x improve in clock pace, reminiscence and flash storage.

This big leap ahead begins with a brand new processor by Renesas, a world chief in microcontrollers, analog, energy and SoC merchandise. Whereas over 10 million customers have loved enjoying and dealing with Arduino UNO R3’s 8-bit microcontroller for greater than a decade, the brand new RA4-series MCU will open up infinite new undertaking alternatives for extra superior makers, and produce the board in control with present requirements.

The UNO R4 will are available in two variations – UNO R4 WiFi and UNO R4 Minima – providing unprecedented efficiency and potentialities for the maker group.

The WiFi model comes with an Espressif S3 WiFi module, increasing inventive alternatives for makers, educators, and hobbyists alike; whereas the UNO R4 Minima gives an economical possibility for these looking for the brand new microcontroller with out extra options.

In particulars, the brand new Arduino UNO R4 options the Renesas RA4M1 (Arm Cortex^®-M4) working at 48MHz, which gives a 3x improve over the UNO R3. Along with that, SRAM went from 2kB to 32kB, and flash reminiscence went from 32kB to 256kB to accommodate extra complicated tasks. As well as, following the requests from the group, the USB port was upgraded to the USB-C and most energy provide voltage was elevated to 24V with an improved thermal design. The board gives a CAN bus, which permits customers to attenuate wiring and execute completely different duties in parallel by connecting a number of shields. Lastly, the brand new board features a 12-bit analog DAC. 

All in all, Arduino UNO R4 is the reply to the requests for enchancment and updates the developer and maker group has been advancing, making it simpler than ever to get began with Arduino.

On the subject of {hardware} compatibility, pinout, voltage and kind issue are unchanged from UNO R3, guaranteeing most {hardware} and electrical compatibility with current shields and tasks.On the software program aspect, an enormous effort is being made to maximize retrocompatibility of the most well-liked Arduino libraries in order that customers will have the ability to depend on current code examples and tutorials. Usually libraries and examples will work out-of-the-box, however just a few of them which had been optimized for the AVR structure utilized in R3 will must be ported. To assist in the transition, Arduino will present a public listing of such libraries, together with hyperlinks to current options. As well as, an early adopter program has been launched – with a devoted web site at www.arduino.cc/UNOR4 – for library builders excited to seek out out extra about UNO R4 and prepared to port their low-level code to the Renesas structure. 

The Arduino UNO R3 will nonetheless be out there and supported, along with all makers who need to work with its 8-bit AVR microcontroller.
