Arduino UNO R4 WiFi

ntroducing 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.

Features:

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
