Project #15: Environment – Arduino UNO R4 WiFi – Mk34

The new Arduino UNO R4 development board UNO R4 WiFi. 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 comes with an Espressif S3 WiFi module, expanding creative opportunities for makers, educators, and hobbyists alike. Based on the success of UNO R3, the UNO R4 board is the ideal prototype and learning tool for anyone. While retaining the well-known features of the UNO series, such as standard form factor, shield compatibility, 5V voltage, and robustness, new features have been added.
