+<p style="text-align: justify;">
 The UNO R4 WiFi is a modern 32-bit development board that combines the performance of the Renesas RA4M1 microcontroller with the wireless connectivity of the ESP32-S3-MINI-1 module. While preserving the classic UNO form factor and 5 V logic compatibility, it introduces new features including a built-in 12x8 LED matrix, CAN bus and QWIIC I2C connector. These additions make it suitable for both traditional prototyping and modern IoT development.
