Introduction

The Arduino UNO R4 WiFi is the first UNO board to feature a 32-bit microcontroller and an ESP32-S3 Wi-Fi module (ESP32-S3-MINI-1-N8). It uses a microcontroller from the RA4M1 series (R7FA4M1AB3CFM#AA0) by Renesas, based on a 48 MHz Arm Cortex-M4 microprocessor. The UNO R4 WiFi has more memory than its predecessors, with 256 kB of flash, 32 kB of SRAM, and 8 kB of EEPROM. The RA4M1 operates at a fixed voltage of 5 V, while the ESP32-S3 module operates at 3.3 V. Communication between the two MCUs is carried out via a logic level converter (TxB0108DQSR). The board has 14 digital I/O ports, 6 analog channels, and pins dedicated to I2C, SPI, and UART connections. It has more memory: 8 times the flash memory (256 kB) and 16 times the SRAM (32 kB) of its predecessors. With a clock speed of 48 MHz, it is also 3 times faster than its predecessors. Additionally, it features an ESP32-S3 module for Wi-Fi and Bluetooth connectivity, as well as a built-in 12x8 LED matrix, making it one of the most visually distinctive Arduino boards to date. The LED matrix is fully programmable, and you can load anything from static frames to custom animations.
