Arduino Nano Original A000005
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. What’s so special about Arduino Nano ? Find out!
