Description Arduino Uno R4 Wi-Fi
This is the Arduino Uno R4 Wi-Fi. With its built-in Wi-Fi® and Bluetooth® capabilities, the UNO R4 WiFi enables seamless wireless communication. This allows you to connect and control your projects remotely. This board combines Renesas' RA4M1 microprocessor with Espressif's ESP32-S3. The UNO R4 WiFi retains the well-known UNO format. It is therefore compatible is with existing shields and accessories. It features expanded memory and a faster clock speed. So you can effortlessly perform complex calculations and tasks. The built-in 12x8 LED matrix provides a bright display to show visual effects. This is also ideal for displaying sensor data without the need for additional hardware. With the addition of a QWIIC connector, the UNO R4 WiFi offers even more versatility. Allowing you to quickly and easily connect to various QWIIC components and sensors. The UNO R4 WiFi includes a debugging mechanism that detects runtime crashes. Based on this, he gives detailed explanations and hints about the line of code that causes the crash. A very welcome improvement over the Uno R3 is that the Uno R4 has a USB-C port. It board can be easily programmed via the free Arduino IDE software. With built-in HID support, you can board simulate a mouse or keyboard when connected to a computer via USB.

Nice new Arduino with built-in WiFi. stepper motor reacts restlessly. This is not with the Uno R3. Still works well. The most important thing is that the WiFi is built-in. LED matrix is funny.
