Arduino UNO Rev4 WiFi, RA4M1, ESP32-S3

Arduino UNO R4 WiFi

The Arduino UNO R4 WiFi combines the computing power and exciting new peripherals of Renesas' RA4M1 microcontroller with the wireless connectivity performance of Espressif's ESP32-S3. In addition, the UNO R4 WiFi features an integrated 12x8 LED matrix, a QWIIC connector, a VRTC pin for a backup battery, and an OFF pin. With the UNO R4 WiFi, you can easily upgrade your project and add wireless connectivity to extend the reach of your current project. If this is your first project, this board simply has everything you need to spark your maximum creativity. Hardware Compatibility with UNO Form Factor The UNO R4 WiFi maintains the same form factor, pinout, and 5V operating voltage as its predecessor the UNO R3. This ensures a seamless transition for existing shields and projects. Expanded memory and faster clock The UNO R4 WiFi has more memory and a higher clock frequency, enabling more precise calculations and effortless processing of complex projects. Additional on-board peripheral capabilities The UNO R4 WiFi offers a range of on-board peripherals, including a 12-bit DAC, CAN-BUS, and OP AMP, providing enhanced capabilities and design flexibility. HID Support Integrated HID support allows the UNO R4 WiFi to simulate a mouse or keyboard via USB-C. Wi-Fi® and Bluetooth® The UNO R4 WiFi features an ESP32-S3 module, enabling wireless connectivity. Combined with the Arduino IoT Cloud, Makers can now monitor and control their projects remotely. QWIIC connector The UNO R4 WiFi features a QWIIC I2C connector that allows for easy connection into the QWIIC ecosystem. Adapter cables allow compatibility with sensors and actuators based on other connector standards. Support for a battery-powered RTC The UNO includes additional pins, such as an "OFF" pin to turn off the board and a "VRTC" pin that powers the internal real-time clock and keeps it running. LED Matrix The UNO R4 WiFi has a bright 12x8 red LED matrix, ideal for creative projects with animations or plotting sensor data without the need for additional hardware. Runtime error diagnostics The UNO R4 WiFi includes an error recovery mechanism that detects runtime crashes and provides detailed explanations with hints on the line of code that caused the crash.
