Arduino UNO R3 with Wi-Fi ATmega328P + ESP8266 NodeMCU

The Arduino UNO R3 with Wi-Fi ATmega328P + ESP8266 NodeMCU is a hybrid development board that combines a traditional ATmega328P-based microcontroller with a built-in ESP8266 NodeMCU WiFi module. This design allows developers to handle both hardware control and wireless communication on a single board.

The ATmega328P chip manages real-time I/O tasks such as reading sensors and controlling actuators, while the ESP8266 handles network connectivity, enabling seamless integration with IoT platforms. Communication between the two controllers is typically done through serial interface, allowing flexible project architecture.

This board eliminates the need for an external arduino wifi module, simplifying wiring and reducing system complexity. It is include with ATmega328P and ESP8266 NodeMCU, making it suitable for developers already familiar with these environments.

Provided by StemVolt, this Arduino board is ideal for IoT developers building smart home systems, remote monitoring, and automation projects with reliable performance.
