Microcontroller: The Arduino Nano A000005 is powered by the ATmega328P microcontroller, which operates at 16MHz and has 32KB of flash memory for storing your code.
Digital Pins: It has 14 digital input/output pins (of which 6 can be used as PWM outputs), allowing you to connect a wide range of sensors, actuators, and other components.
Analog Inputs: The Nano has 8 analog inputs, which can be used to read analog signals from sensors like temperature sensors, light sensors, etc.
Voltage Regulator: The onboard voltage regulator allows you to power the board using an external power source (7-12V) or through the USB connector (5V).
USB Interface: The Nano has a mini-USB connector that can be used to upload code to the board and to power it.
Serial Communication: The Nano features UART (Universal Asynchronous Receiver-Transmitter) pins that enable serial communication, which is useful for communication with other devices, debugging, and more.
Flash Memory: The ATmega328P has 32KB of flash memory, which is where your code is stored. This should be sufficient for many projects.
