Abstract :
The rapid growth of IoT applications demands development boards with higher performance and better connectivity. Arduino Uno has been widely used for prototyping and educational purposes. However, its limited processing power and lack of built-in wireless communication restrict advanced applications. The ESP32-powered development board emerges as a powerful upgrade to Arduino Uno. ESP32 integrates Wi-Fi and Bluetooth on a single chip. It offers higher clock speed and dual-core processing. The board supports low-power modes suitable for IoT devices. Improved memory capacity allows complex program execution. ESP32 enables real-time data communication. It supports cloud-based applications seamlessly. The board is cost-effective and compact. Built-in security features enhance data protection. ESP32 supports multiple communication protocols. It allows faster data processing than Arduino Uno. This study compares Arduino Uno and ESP32 capabilities. The proposed upgrade improves connectivity
