Arduino UNO R4 WiFi Development Board

##Introduction Expected delivery: AugustThe new Arduino UNO R4 development board 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 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.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.Figure: Board Overview ProductUno R4Uno R3CPURenesas RA4M1 (48 MHz, Arm Cortex M4)ATmega328P (16 MHz, AVR)SRAM32K2KFlash Storage256K32KUSBType-CType-BMax Voltage24V20V ##Features Hardware compatibility with UNO form factor The UNO R4 WiFi maintains thesame form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3,ensuring a seamless transition for existing shields and projects.Expanded memory and faster clockThe UNO R4 WiFi boasts increased memoryand a faster clock speed, enabling more precise calculations and effortless handlingof complex projects.Extra on-board peripheralsThe UNO R4 WiFi introduces a range of on-boardperipherals, including a 12-bit DAC, CAN BUS, and OP AMP, providing expandedcapabilities and design flexibility.Extended 24 V toleranceThe UNO R4 WiFi supports a wider input voltage range,allowing seamless integration with motors, LED strips, and other actuators using asingle power source.HID supportWith built-in HID support, the UNO R4 WiFi can simulate a mouse orkeyboard when connected to a computer via USB, making it easy to send keystrokesand mouse movements.Wi-Fi® and Bluetooth®The UNO R4 WiFi hosts an ESP32-S3 module, enablingmakers to add wireless connectivity to their projects.
