Here are the key features and components of this board:

ATmega328P Microcontroller: The Nano board is typically equipped with an ATmega328P microcontroller, which is the same microcontroller used in the Arduino Uno. It runs at 16 MHz and has 32KB of flash memory, 2KB of SRAM, and 1KB of EEPROM. This microcontroller is the core of the board and executes the program logic.

CH340 USB-to-Serial Converter: The board includes a CH340 USB-to-Serial converter chip. This chip allows you to connect the Nano board to a computer via a Mini-USB port for programming and serial communication. You may need to install CH340 drivers on your computer, depending on your operating system.

Mini-USB Port: The Mini-USB port serves as the primary interface for connecting the Nano board to a computer. It is used for uploading sketches (programs) to the board and for serial communication with the microcontroller.

Compact Form Factor: The Nano board is small in size, making it suitable for projects with limited space requirements. Its form factor is similar to the Arduino Nano, which is known for its compact design.

GPIO Pins: The board features a set of GPIO (General Purpose Input/Output) pins, including digital pins, analog pins, and power pins. These pins allow you to connect various sensors, actuators, and other electronic components to the board.
