Description

The Arduino Uno R4 WiFi with USB-C Cable is a powerful upgrade to the classic Uno platform, designed for makers, hobbyists, and engineers seeking enhanced performance and connectivity. Powered by a 32-bit Renesas RA4M1 microcontroller (Arm Cortex-M4) with a 48MHz clock speed, 256KB flash, and 32KB SRAM, it offers increased processing power and memory compared to its predecessors. Integrated with an ESP32-S3 coprocessor, it provides built-in WiFi (802.11 b/g/n) and Bluetooth 5.0, enabling seamless IoT projects, remote control, and wireless data transfer. The board retains the familiar Uno form factor and 5V operating voltage, ensuring compatibility with existing Uno R3 shields and projects, while introducing advanced features like a 12×8 red LED matrix for animations and data visualization, a Qwiic I2C connector for easy sensor integration, and a battery-powered Real-Time Clock (RTC) with VRTC and OFF pins.

Additional perks include a 12-bit DAC for audio projects, CAN bus support for robust communication, an OP AMP for signal processing, and a 24V tolerance for powering motors or LED strips with a single supply. The USB-C port facilitates fast programming and power delivery, with the included cable ensuring immediate usability. Operating from -40°C to +85°C, this RoHS-compliant board weighs approximately 25g and measures 68.6×53.4mm. For Arduino use, connect it via USB-C to your computer, install the R4 board definitions in the Arduino IDE, and leverage libraries like WiFi.h for network tasks or FastLED for LED matrix control. Ideal for drones, smart home devices, and educational projects, it pairs well with your TDA2030 module for audio output or NEO-7M for location tracking.

Note: The ESP32-S3 operates at 3.3V, requiring level shifting for 5V peripherals on the Qwiic connector, and a heat sink is recommended for high-load scenarios.
