The historical past of creating is now prepared for the longer term: a 32-bit UNO will quickly be accessible due to a strong Renesas processor
Right here at Arduino we’re thrilled to announce a brand new, revolutionary revision of the enduring UNO board, which is able to develop the idea of the open-source model’s most iconic and standard 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 – customary kind issue, defend compatibility, 5V working voltage, excellent robustness – whereas providing at least a 32-bit Cortex®-M4 and a 3-to-16x enhance in clock velocity, reminiscence and flash storage.
This large 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 taking part in and dealing with Arduino UNO R3’s 8-bit microcontroller for greater than a decade, the brand new RA4-series MCU will open up limitless new mission alternatives for extra superior makers, and produce the board on top of things with present requirements.
The UNO R4 will are available 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 artistic alternatives for makers, educators, and hobbyists alike; whereas the UNO R4 Minima offers a cheap possibility for these in search of 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 offers a 3x enhance 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 initiatives. 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 offers a CAN bus, which permits customers to attenuate wiring and execute totally 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.
With regards to {hardware} compatibility, pinout, voltage and kind issue are unchanged from UNO R3, guaranteeing most {hardware} and electrical compatibility with present shields and initiatives.On the software program aspect, an enormous effort is being made to maximize retrocompatibility of the preferred Arduino libraries in order that customers will be capable to depend on present code examples and tutorials. Generally libraries and examples will work out-of-the-box, however a couple of of them which have been optimized for the AVR structure utilized in R3 will have to be ported. To assist in the transition, Arduino will present a public checklist of such libraries, together with hyperlinks to present 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 search out out extra about UNO R4 and keen to port their low-level code to the Renesas structure.
The Arduino UNO R3 will nonetheless be accessible and supported, together with all makers who wish to work with its 8-bit AVR microcontroller.
Arduino UNO R4 is scheduled for launch in late Could, when extra particulars about its options will probably be disclosed, however you possibly can already subscribe the ready checklist and get notified when in inventory!
