The new Arduino UNO R4 comes in two versions: the UNO R4 WiFi and the UNO R4 Minima. It runs on the Renesas RA4M1 (Arm Cortex-M4) processor, with a clock speed of 48MHz, which provides a 3x increase over the UNO R3. In addition to that, the SRAM has been upgraded from 2kB to 32kB and the flash memory has been increased from 32kB to 256kB to accommodate to more complex projects. Furthermore, in response to requests from the Arduino community, the USB port has been upgraded to USB-C and the maximum power supply voltage has been increased to 24V. The board provides a CAN bus, allowing users to minimize wiring and perform different tasks by connecting multiple extension boards. Finally, the new board also includes a 12-bit analog DAC.
[] The WiFi version is equipped with the Espressif S3 WiFi module, providing manufacturers, educators, and enthusiasts with more creative opportunities.
[] The UNO R4 Minima provides a cost-effective option for those seeking new microcontrollers without additional features.
[] Building on the success of UNO R3, UNO R4 is the best prototype and learning tool for everyone. While retaining the known characteristics of the UNO series (standard form factor, shielding compatibility, 5V voltage, robustness), new features have been added.
[] Thanks to its powerful design and reliable performance, the UNO R4 is a valuable addition to the Arduino ecosystem, suitable for beginners and experienced electronics enthusiasts alike to deploy their own projects.
