The Arduino UNO R4 WiFi is the latest and more powerful member of the UNO family. It combines the processing power and exciting new peripherals of the RA4M1 microcontroller from Renesas with the wireless connectivity power of the ESP32-S3 from Espressif. On top of this, the UNO R4 WiFi offers an on-board 12x8 LED matrix, Qwiic connector, VRTC, and OFF pin, covering all potential needs makers will have for their next project. With the UNO R4 WiFi, you can easily upgrade your project and add wireless connectivity to expand the reach of your current setup. If this is your first project, this board has everything you need to spark your creativity. The UNO R4 WIFI is compatible with Arduino Cloud to enhance your connected projects quickly. With Arduino Cloud, you can visualize your sensor data with stunning dashboards, control and monitor your devices from anywhere and enjoy over-the-air updates. This bundle includes an Arduino UNO R4 WIFI and an Arduino Cloud Maker plan. The Maker plan is the right choice for users with medium-size projects who don't want to worry about storage or compilation limits and want to use all the advanced features of the platform such as real-time notifications and advanced widgets. Let's explore the key features of the UNO R4 WIFI: Hardware compatibility with UNO form factor, keeping the same pinout and 5 V operating voltage as its predecessors. Expanded memory and faster clock to enable more precise calculations and to effortlessly handle complex projects. Extra on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP, providing expanded capabilities and design flexibility. Extended 24 V tolerance, allowing seamless integration with motors, LED strips, and other actuators using a single power source. HID support that can simulate a mouse or keyboard when connected to a computer via USB. Wi-Fi® and Bluetooth® through an embedded ESP32-S3 module. Qwiic connector. Support for battery-powered RTC. A bright 12x8 red LED matrix, ideal for creative projects with animations or plotting sensor data, eliminating the need for additional hardware. Diagnostics for runtime errors with error-catching mechanism that detects runtime crashes and provides detailed explanations and hints about the code line causing the crash. 1-year subscription to the Arduino Cloud Maker Plan With the 1-year subscription to the Maker plan you can: Manage 25 devices at a time with unlimited variables Get unlimited Cloud storage for your sketches Enjoy unlimited Cloud compilations Receive 100 real-time notifications per day Access advanced widgets (such as Advanced Chart widget) Share your IoT monitoring dashboards with anyone Share your sketches with anyone Enjoy Over-the-air (OTA) updates Benefit from Arduino Cloud API support (10 requests per second) Collect 3 months of data retention
