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 equips 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.


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