Review: Really great all round board for beginner and experienced user. - This was a great price for a genuine Arduino board. The board is a great 1st time board as it not only has WiFi and Bluetooth but also has two processors that can be utilised separately if you choose to not use Bluetooth and WiFi. The onboard LEDs make playing with the board quick and fun for beginners. There are so many features on board. The only word of caution is the max amount of amps on the pins has dropped considerably so bigger resistors will be needed, this is important as sketches for the UNO r3 work with 5v and 20 milli amps. This board has maximum 8 milliamps. And the esp32 chip uses only 3.3v. So you just need to check before turning on your projects. Great board though! So always recheck before turning on your projects.

## Features

- Dual-Core Processing with Renesas RA4M1 and ESP32-S3: The Arduino UNO R4 WiFi combines the Renesas RA4M1 microcontroller (ARM Cortex-M4) and the ESP32-S3 Wi-Fi/Bluetooth chip, delivering powerful dual-core processing capabilities. This combination offers flexibility for a wide range of projects, from high-speed communications and wireless control to real-time data processing and edge AI applications.
