Featuring a high-precision 12-bit DAC, OP-AMP, and an integrated 12x8 LED matrix, it’s designed for professional-grade IoT and embedded projects with seamless backward compatibility and easy expansion. ## Description Arduino was born at the Ivrea Interaction Design Institute as an easy tool for fast prototyping, aimed at students without a background in electronics and programming. Thanks to its simple and accessible user experience, Arduino has been used in thousands of different projects and applications. The Arduino software is easy-to-use for beginners, yet flexible enough for advanced users. Our vision is to make Arduino available to everyone, whether you are a student, maker or professional. The Arduino Uno R4 WiFi is the premium version of the new UNO R4 line. It combines the powerful Renesas RA4M1 microcontroller with an ESP32-S3 module, offering advanced Wi-Fi and Bluetooth capabilities, plus a built-in LED matrix. The Arduino Uno R4 Minima is the cost-effective option in the UNO R4 family. It features the powerful 32-bit Renesas RA4M1 microcontroller, maintaining the classic UNO form factor and providing a seamless upgrade path for projects. The integrated enables seamless wireless communication, allowing you to connect to the Internet and interact via Bluetooth. Both boards are compatible with the , providing an easy and intuitive way to program, monitor, and manage your projects from anywhere. Both boards feature a new DCDC converter, allowing them to handle up to 24V. This simplifies projects with motors or LED strips. Both boards feature a speed and , allowing for more precise calculations and larger projects. What is the main difference between the Uno R4 WiFi and the Uno R4 Minima? The Uno R4 WiFi includes an on-board ESP32-S3 for Wi-Fi and Bluetooth, plus an LED matrix. The Uno R4 Minima is a more cost-effective version without these features. Is the Arduino Uno R4 series backward compatible with my old projects? Yes, the Uno R4 boards maintain the same form factor, pinout, and 5V operating voltage as the UNO R3, ensuring compatibility with your existing shields and projects. What is the Qwiic connector for? The Uno R4 WiFi's Qwiic connector allows for quick plug-and-play integration with a vast ecosystem of I2C sensors and modules, including our own Arduino Modulinos. How does the Uno R4 compare to the original Uno R3? The Uno R4 is a significant upgrade with a faster 32-bit processor, more memory, and new features like a DAC and CAN Bus, while keeping the classic 5V operating voltage. ## Features - Dual-Core Processing with Renesas RA4M1 and ESP32-S3: The Arduino UNO R4 WiFi combines the Renesas RA4M1 microcontroller (ARM Cortex-M4) and the ESP32-S3 Wi-Fi/Bluetooth chip, delivering powerful dual-core processing capabilities. This combination offers flexibility for a wide range of projects, from high-speed communications and wireless control to real-time data processing and edge AI applications. - Comprehensive Wireless Connectivity: Equipped with Wi-Fi and Bluetooth 5.0, the UNO R4 WiFi ensures robust wireless communication for IoT projects, remote sensors, smart devices, and wireless control applications. Whether connecting to the cloud, other devices, or local networks, the board offers stable and high-speed wireless connectivity for seamless operation. - Modern USB-C, CAN, & Qwiic Connector: The USB-C port enables efficient power delivery and fast programming, improving ease of use compared to traditional USB connections. The Controller Area Network (CAN) support allows for reliable, real-time communication in industrial, automotive, or robotic systems. Additionally, the Qwiic Connector makes it easy to add I2C sensors and peripherals, simplifying the connection process and reducing the need for complex wiring. - High-Precision 12-bit DAC & OP-AMP: For projects that require high-quality analog output, the 12-bit DAC (Digital-to-Analog Converter) and integrated operational amplifier (OP-AMP) provide precise analog signal generation and amplification. This feature is ideal for audio projects, sensor interfacing, or applications where analog signal control and processing are necessary. - Integrated 12x8 LED Matrix: The UNO R4 WiFi includes a built-in 12x8 LED Matrix, enabling users to display dynamic visuals, messages, or real-time data on the board itself. This makes it perfect for projects that require immediate visual feedback, such as status indicators, event displays, or interactive user interfaces. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0C8V88Z9D | | Best Sellers Rank | #10 in Single Board Computers (Computers & Accessories) | | Brand | Arduino | | Built In Media | Industrial extension module | | Compatible Devices | Devices with UART, SPI, I2C, or CAN interfaces | | Connectivity Technology | Bluetooth, USB, Wi-Fi | | Customer Reviews | 4.8 4.8 out of 5 stars (2,084) 4.8 out of 5 stars | | External Testing Certification | NΓ£o aplicΓ‘vel | | Item Dimensions L X W X H | 8"W x 1.57"H | | Item Weight | 20 Grams | | Manufacturer | Arduino | | Mfr Part Number | ABX00087 | | Model Name | Arduino UNO R4 WiFi | | Model Number | ABX00087 | | Operating System | FreeRTOS | | Processor Count | 1 | | Ram Memory Technology | SRAM | | Smart Home Compatibility | Not Smart Home Compatible | | Total Usb Ports | 1 | | Warranty Description | 2 Year Manufacturer | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** Arduino - **Connectivity Technology:** Bluetooth, USB, Wi-Fi - **Included Components:** Industrial extension module - **Model Name:** Arduino UNO R4 WiFi - **Operating System:** FreeRTOS ## Images ![UNO R4 WiFi [ABX00087] - Renesas RA4M1 + ESP32-S3, Wi-Fi, Bluetooth, USB-C, CAN, 12-bit DAC, OP AMP, Qwiic Connector, 12x8 LED Matrix for Advanced IoT & Embedded Projects - Image 1](https://m.media-amazon.com/images/I/614tXIQWSRL.jpg) ## Questions & Answers **Q: What is the main difference between the Uno R4 WiFi and the Uno R4 Minima?** A: The Uno R4 WiFi includes an on-board ESP32-S3 for Wi-Fi and Bluetooth, plus an LED matrix.
