Arduino Nano V3 ATmega328P Mini Microcontroller Core Board with CH340 Chip

Product Description

Product Overview

The Arduino Nano V3 is a small, compact microcontroller board that is part of the Arduino family. It is based on the ATmega328P microcontroller, which is a popular choice for DIY electronics projects and has been a staple in the Arduino ecosystem for many years. 

Key Features

1. Processor: Equipped with the ATmega328P microcontroller featuring 14 digital I/O pins, 6 of which can provide PWM output, and 8 analog input pins.

2. Memory: Includes 32 KB of flash memory for storing code, 2 KB of RAM for variables, and 1 KB of EEPROM.

3. Form Factor: It has a mini form factor with a smaller PCB, making it easy to use in tight spaces or when miniaturization is desired.

4. Programmability: It can be programmed with the Arduino IDE through a USB connection, using the on-board ATmega328P's bootloader.

5. Power: Operates at 5V and uses a Mini-B USB connector for power and programming.

6. Features: It has a reset button, a 16 MHz ceramic resonator, and a pad for an external capacitor if needed.

7. Applications: Ideal for small projects that require a lot of I/O in a small form factor, such as robots, sensors, and interactive electronic devices.

8. Community: Benefits from a large community of users and developers, with a wealth of tutorials, libraries, and examples available online.

9. Upgraded Version: The V3 version of the Arduino Nano includes improvements over previous versions, such as better power management and a more reliable bootloader.

10. Pinouts: It retains the classic Arduino pinout, making it compatible with a wide range of shields and expansion boards.
