The Arduino Nano V3 is a compact and versatile board based on the ATmega328 microcontroller. It is designed to be small and easily compatible with breadboards. The Arduino Nano V3 shares similar functionality with the Arduino UNO, but comes in a different form factor. The Nano programming module does not include a DC power jack, instead using a Mini-B USB cable for power.

The specifications of the Arduino Nano V3 with USB Cable are as follows:

• Microcontroller: ATmega328 (Arduino Nano)
• Operating Voltage (logic level): 5V
• Recommended Input Voltage: 7-12V
• Input Voltage Limits: 6-20V
• Digital I/O Pins: 14 (6 of which provide PWM output)
• Analog Input Pins: 8
• Maximum DC Current per I/O Pin: 40mA
• Flash Memory: 16KB (ATmega168) or 32KB (ATmega328), with 2KB used by the bootloader
• SRAM: 1KB (ATmega168) or 2KB (ATmega328)
• EEPROM: 512 bytes (ATmega168) or 1KB (ATmega328)
• Clock Speed: 16MHz

The Arduino Nano V3 ATmega328P Development Board offers several features:

• Automatic reset during program download.
• Power OK blue LED indicator.
• LEDs for TX (green), RX (red), and L (orange) signaling.
• Auto-sensing/switching power input.
• Small mini-B USB connector for programming and serial monitor.
• ICSP header for direct program download.
• Standard 0.1″ spacing DIP format, suitable for breadboard usage.
• Manual reset switch.
