Introducing the latest addition to the Arduino lineup, the Arduino UNO R4 WiFi board. This new version of the UNO board brings significant advancements, making it a powerful tool for your projects. The standout feature of the UNO R4 WiFi is the integration of an ESP32-S3 Wi-Fi module (ESP32-S3-MINI-1-N8) which equip the UNO with Inbuilt Bluetooth and WiFi.
The UNO R4 WiFi is part of the first UNO series of 32-bit development boards, being previously based on 8-bit AVR microcontrollers. There are thousands of guides, tutorials, and books written about the UNO board, where the UNO R4
WiFi continues its legacy.
Pin Configuration:
Powered by a 48 MHz Arm® Cortex®-M4 microprocessor, the board utilizes a RA4M1 series microcontroller from Renesas (R7FA4M1AB3CFM#AA0). With enhanced memory capabilities, the UNO R4 WiFi boasts 256 kB flash, 32 kB SRAM, and 8 kB of EEPROM. Additionally, a logic level translator (TXB0108DQSR) facilitates seamless communication between the RA4M1 and ESP32-S3 modules, ensuring optimal performance. Upgrade to the Arduino UNO R4 WiFi and experience the next level of Arduino innovation.
