Arduino Uno Rev4 Wifi

The Arduino UNO R4 WiFi merges the RA4M1 microprocessor from Renesas with the ESP32-S3 from Espressif, creating an all-in-one tool for makers with enhanced processing power and a diverse array of new peripherals. With its built-in Wi-Fi® and Bluetooth® capabilities, the UNO R4 WiFi enables makers to venture into boundless creative possibilities. Furthermore, this versatile board boasts a convenient on-board 12x8 LED matrix and a Qwiic connector, offering ample space for innovation and unleashing creativity. This dynamic combination empowers makers to transform their ideas into reality and elevate their projects to unprecedented heights.

Hardware compatibility: Maintains the same form factor, pinout, and 5 V operating voltage as its predecessor, the UNO R3, ensuring a seamless transition for existing shields and projects.

Increased memory and a faster clock speed, enabling more precise calculations and effortless handling of complex projects.

Introduces a range of on-board peripherals, including a 12-bit DAC, CAN BUS, and OP AMP, providing expanded capabilities and 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, the UNO can simulate a mouse or keyboard when connected to a computer via USB, making it easy to send keystrokes and mouse movements.

ESP32-S3 module, enabling makers to add wireless connectivity to their projects. Combined with the Arduino IoT Cloud, makers can monitor and control their projects remotely.

Featuring a Qwiic I2C connector, allowing easy connection to nodes from the extensive Qwiic ecosystem. Adapter cables also enable compatibility with sensors and actuators based on other connectors.

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.

Incorporates a bright 12x8 red LED matrix, ideal for creative projects with animations or plotting sensor data, eliminating the need for additional hardware.

Includes an error-catching mechanism that detects runtime crashes and provides detailed explanations and hints about the code line causing the crash.
