It combines a Renesas RA4M1 microcontroller with an ESP32-S3 module for WiFi and Bluetooth LE. This board offers a familiar UNO footprint with modern 32-bit performance and wireless connectivity for IoT projects.\u003c\/p\u003e\n\n\u003ch2\u003eKey Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMicrocontroller\u003c\/td\u003e\n\u003ctd\u003eRenesas RA4M1 (Arm Cortex-M4)\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eClock Speed\u003c\/td\u003e\n\u003ctd\u003e48 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFlash Memory\u003c\/td\u003e\n\u003ctd\u003e256 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eSRAM\u003c\/td\u003e\n\u003ctd\u003e32 KB\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eWireless\u003c\/td\u003e\n\u003ctd\u003eESP32-S3 (WiFi 802.11 b\/g\/n, BLE 5.0)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWhat You Can Build With This\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-home-security-motion-sensor-kit-with-esp32\"\u003eSmart home sensor hub that reports temperature, humidity, and motion to the cloud\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eWiFi-controlled robot with real-time video streaming\u003c\/li\u003e\n  \u003cli\u003eBluetooth low energy beacon for indoor positioning\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"\/products\/kit-indoor-weather-station\"\u003eIoT weather station that publishes data to a web dashboard\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThe board operates at 5V logic and is compatible with most existing Arduino UNO R3 shields. It works in the Arduino IDE 2.x and can be programmed via USB-C or over-the-air updates. Standard 5V sensors, servos, and LCD displays pair directly with the I\/O headers.\u003c\/p\u003e\n\n\u003ch2\u003eWiring Notes\u003c\/h2\u003e\n\u003cp\u003eUse the USB-C port for power and programming; the onboard regulator accepts 7-12V on the VIN pin. Digital I\/O pins can source up to 20 mA each. The ESP32-S3 antenna is located near the reset button—keep clear of metal enclosures to maintain signal strength.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy from Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.\u003c\/p\u003e\n\n\u003cdetails\u003e\u003csummary\u003eIs this compatible with Arduino UNO R3 shields?\u003c\/summary\u003e\u003cp\u003eYes, the Arduino UNO R4 WiFi uses the same pinout as the R3, so most 5V-compatible shields plug directly in. Check the shield’s logic voltage if it uses 3.3V only.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eDoes this board have built-in WiFi and Bluetooth?\u003c\/summary\u003e\u003cp\u003eYes, the onboard ESP32-S3 module provides 2.4 GHz WiFi (b\/g\/n) and Bluetooth Low Energy 5.0 connectivity without extra hardware.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat programming environment do I need?\u003c\/summary\u003e\u003cp\u003eUse the Arduino IDE 2.0 or later, available for Windows, macOS, and Linux.
