Arduino UNO R4 WiFi Development Board – Built-In WiFi Connectivity

QAR 175.00/ unit

Description

The Arduino UNO R4 WiFi is an advanced development board designed for embedded and connected applications. It is powered by the Renesas RA4M1 Arm Cortex-M4 microcontroller running at 48 MHz, with expanded memory resources including 32 kB SRAM and 256 kB flash. The board features a USB-C interface, supports input voltages up to 24 V, and includes CAN bus and a 12-bit DAC for extended system control. It integrates an Espressif ESP32-S3 module to provide built-in WiFi connectivity. Fully compatible with Arduino UNO R3 shields and 5 V logic, it is suitable for engineering education, IoT prototyping, and professional development projects.
