Arduino Nano Unsoldered Board

An unsoldered Arduino Nano board is essentially an Arduino Nano that has had its header pins removed. This can be useful if you want to integrate the Nano into a custom PCB or project without the bulk of the headers. The Arduino Nano is a small, complete, and breadboard-friendly microcontroller board based on the ATmega328P or ATmega168, designed for projects where space is at a premium. Here’s a detailed overview of its features, setup, and applications:

Key Features
Microcontroller: ATmega328P or ATmega168, depending on the version.

Operating Voltage: 5V, which is standard for most Arduino projects.

Input Voltage: 7-12V (recommended) via an external power supply, with a maximum limit of 6-20V.

Digital I/O Pins: 14 digital pins, 6 of which provide Pulse Width Modulation (PWM) output.

Analog Input Pins: 8 analog input pins that provide 10-bit resolution, useful for reading sensors and other analog devices.

Flash Memory: 32 KB (ATmega328P) or 16 KB (ATmega168), with 2 KB used by the bootloader.

SRAM: 2 KB (ATmega328P) or 1 KB (ATmega168).

EEPROM: 1 KB (ATmega328P) or 512 bytes (ATmega168).

Clock Speed: 16 MHz, ensuring quick and efficient processing.
