Product details
Arduino Nano Original A000005
The Arduino Nano is a compact, open-source development board based on ATmega328P, an 8-bit AVR microcontroller.
It has 14 digital I/O pins, 8 analog input pins with 10-bit resolution, 2 reset pins, and 6 power pins, making it perfect for space-constrained projects that require fewer GPIOs and memory.
The Arduino Nano board operates at 5V, supports an input voltage of 6V–20V (recommended: 7V–12V), and runs at a 16 MHz clock frequency. Unlike most Arduino boards, it uses a mini USB port and lacks a DC power jack, so it cannot be powered through an external jack.
Fully breadboard-friendly, the Nano is perfect for quick prototyping. It offers flash memory of 32KB (with 2KB used by the bootloader), EEPROM of 512B/1KB, and SRAM of 1KB/2KB, depending on the microcontroller.
The Arduino Nano microcontroller delivers Arduino Uno-like performance in a smaller, more project-ready form.
