Both microcontrollers can work together or independently, each with its own pinout headers for easy peripheral connections. A built-in CH340G USB-TTL converter allows you to program and communicate with either controller via USB.
The onboard DIP switch makes it easy to select operating modes such as programming the ATmega328P, flashing the ESP8266, enabling serial communication between them, or running both modules independently. This board is an ideal solution for projects that require Arduino compatibility with Wi-Fi connectivity.
