The Arduino UNO R4 WiFi combines the processing power of the Renesas RA4M1 microcontroller with the wireless connectivity of the ESP32-S3 module by Espressif. It also features an integrated 12x8 LED matrix, a Qwiic connector, VRTC, and an OFF pin, covering all the needs creators may have for their upcoming projects.
It retains the same form factor, pinout, and 5V operating voltage as its predecessor, the UNO R3, ensuring a smooth transition for existing shields and projects.
It boasts increased memory and faster clock speeds, enabling precise calculations and efficient handling of complex projects.
It introduces a variety of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP, offering expanded capabilities and greater design flexibility.
Supports a wider input voltage range, allowing seamless integration with motors, LED strips, and other actuators using a single power source.
With built-in HID support, it can emulate a mouse or keyboard when connected to a computer via USB, making it easy to send keystrokes and mouse movements.
Equipped with an ESP32-S3 module, it enables makers to add wireless connectivity to their projects. Combined with Arduino IoT Cloud, it allows remote monitoring and control of projects.
It features a Qwiic I2C connector, facilitating connections to nodes from the extensive Qwiic ecosystem. Adapter cables also enable compatibility with sensors and actuators based on other connectors.
Includes additional pins, such as an "OFF" pin to turn off the board and a "VRTC" pin to keep the internal Real-Time Clock powered and running.
Features a bright 12x8 red LED matrix, perfect for creative projects involving animations or displaying sensor data, eliminating the need for extra hardware.
Includes a mechanism to detect runtime crashes, providing detailed explanations and suggestions regarding the specific line of code causing the error.
With all these features integrated into the familiar UNO form factor, now is the perfect time to upgrade your project or start your maker journey. The UNO R4 WiFi offers unmatched versatility and possibilities for makers of all levels.
