Arduino UNO R4 WiFi combines Renesas' RA4M1 microprocessor with Espressif's ESP32-S3, creating an all-in-one tool for makers with increased processing power and a wide range of new peripherals. With built-in Wi-Fi® and Bluetooth® capabilities, UNO R4 WiFi allows makers to venture into endless creative possibilities. In addition, this versatile board boasts a convenient on-board 12x8 LED matrix and Qwiic connector, providing ample room for innovation and creativity. This dynamic combination allows makers to turn their ideas into reality and elevate their designs to unprecedented heights.
Let's find out what UNO R4 WiFi offers:
Hardware compatibility with the UNO form factor: The UNO R4 WiFi maintains the same form factor, pinout, and 5V operating voltage as its predecessor, the UNO R3, ensuring a seamless transition for existing shields and designs.
Expanded memory and faster clocking: The UNO R4 WiFi boasts increased memory and higher clock speed, enabling more accurate calculations and easier handling of complex designs.
Additional on-board peripherals: The UNO R4 WiFi introduces a number of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP, offering greater functionality and design flexibility.
Extended 24V tolerance: The UNO R4 WiFi supports a wider input voltage range, enabling seamless integration with motors, LED strips, and other actuators using a single power source.
HID Support: With built-in HID support, the UNO R4 WiFi can simulate a mouse or keyboard when connected to a computer via USB, making it easy to send keystrokes and mouse movements.
Wi-Fi® and Bluetooth®: UNO R4 WiFi houses an ESP32-S3 module, enabling makers to add wireless connectivity to their designs. Combined with Arduino IoT Cloud, makers can monitor and control their projects remotely.
Qwiic connector: UNO R4 WiFi comes with a Qwiic I2C connector, allowing easy connection to nodes in the broad Qwiic ecosystem. Adapter cables also enable compatibility with sensors and actuators based on other connectors.
Support for battery-powered RTC: UNO R4 WiFi includes additional pins, including an "OFF" pin to turn off the board and a "VRTC" pin to keep the internal real-time clock powered and running.
LED matrix: UNO R4 WiFi incorporates a bright red 12x8 LED matrix, ideal for creative projects with animations or for tracking sensor data, eliminating the need for additional hardware.
Runtime Error Diagnostics: UNO R4 WiFi includes an error catching mechanism that detects runtime crashes and provides detailed explanations and hints about the line of code that caused the crash.
