Original Arduino Uno R4 WiFi ABX00087
Introducing the latest addition to the Arduino lineup, the Arduino UNO R4 WiFi board, which represents a significant leap forward in functionality and capabilities. Building upon the rich heritage of the UNO series, this advanced version incorporates cutting-edge features to empower your projects with remarkable efficiency.
The key highlight of the UNO R4 WiFi lies in the seamless integration of the ESP32-S3 Wi-Fi module (ESP32-S3-MINI-1-N8), bestowing the UNO with built-in Bluetooth and Wi-Fi functionalities. This integration ensures a comprehensive connectivity solution for enhanced versatility and convenience.
As a member of the first UNO series of 32-bit development boards with WiFi, the UNO R4 WiFi microcontroller marks a departure from its predecessors, which relied on 8-bit AVR microcontrollers. Leveraging a robust 48 MHz Arm Cortex-M4 microprocessor, this board leverages the prowess of the Renesas RA4M1 series microcontroller (R7FA4M1AB3CFM#AA0).
Its expanded memory capabilities are truly impressive, featuring 256 kB flash, 32 kB SRAM, and 8 kB of EEPROM. To facilitate seamless and efficient communication between the RA4M1 and ESP32-S3 modules, a reliable logic level translator (TXB0108DQSR) is employed, ensuring optimal performance at all times.
Upgrade to the Arduino UNO R4 WiFi microcontroller board today and unlock an unparalleled level of innovation within the realm of Arduino, ushering in a new era of limitless possibilities for your projects.
