Original Arduino Uno R4 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 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.
