UNO R4 WiFi Development Board Compatible

This UNO R4 WiFi compatible development board is designed to provide the same functionality as the official Arduino UNO R4 WiFi while offering additional practical improvements for developers and hobbyists. It integrates an ARM Cortex-M4 processor for high-speed processing together with an ESP32-S3-MINI wireless module for advanced WiFi and Bluetooth connectivity. The board includes a built-in 12x8 LED matrix composed of 96 red LEDs, allowing visual output and display applications without requiring external display modules. Additional GPIO headers simplify sensor and peripheral connections, making prototyping easier and more flexible. Unlike some official versions requiring soldering for certain configuration changes, this improved design incorporates a convenient dial switch for easier operation and communication mode selection.
