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.


Arduino UNO R3 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:

Arduino UNO R4 wifi PIN configPowered 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.


  1. The UNO R4 is now a 32-bit Microcontroller board, being previously based on 8-bit AVR
  2. The board features 14 digital I/O ports, 6 analog channels
  3. Dedicated pins for I2C, SPI and UART connections.
  4. It has a significantly larger memory:
    1. 8 times more flash memory (256 kB)
    2. 16 times more SRAM (32 kB).
  5. Fastest  48 MHz clock Speed. It is 3x faster than its predecessors.
  6. Onboard ESP32-S3 module for Wi-Fi & Bluetooth connectivity,
  7. Onboard 12×8 LED matrix
    1. Making one of the most visually unique Arduino boards to date.
    2. The LED matrix is fully programmable, where you can load anything from still frames to custom animations.
