For the first time in the UNO family, this board transitions from an 8-bit AVR architecture to a powerful \u003cstrong\u003e32-bit Arm® Cortex®-M4 microcontroller\u003c\/strong\u003e, delivering significantly higher performance, expanded memory, and modern connectivity. \u003cbr\u003e\u003cbr\u003ePowered by the \u003cstrong\u003eRenesas RA4M1 (R7FA4M1AB3CFM)\u003c\/strong\u003e running at \u003cstrong\u003e48 MHz\u003c\/strong\u003e, the UNO R4 WiFi features \u003cstrong\u003ebuilt-in Wi-Fi and Bluetooth® 5\u003c\/strong\u003e through an onboard \u003cstrong\u003eESP32-S3-MINI-1\u003c\/strong\u003e module. A dedicated \u003cstrong\u003elogic level translator (TXB0108)\u003c\/strong\u003e ensures seamless communication between the 5 V RA4M1 MCU and the 3.3 V ESP32-S3 module. \u003cbr\u003e\u003cbr\u003eMaintaining the same \u003cstrong\u003eUNO R3 form factor\u003c\/strong\u003e, the UNO R4 WiFi is backward-compatible with most existing shields, while introducing exciting new features such as a \u003cstrong\u003efully programmable 12×8 LED matrix\u003c\/strong\u003e, CAN bus support, DAC output, RTC, and capacitive touch sensing—making it one of the most feature-rich UNO boards ever released.\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv
