Ultra‑Compact Arduino Nano – 32‑bit Controllability in a Tiny Footprint

The Arduino Nano is a pocket‑size microcontroller board powered by the ATmega328P, delivering full Arduino AVR Compatibility in a 1.8 × 0.7 in. footprint. It bridges the gap between simple hobbyist projects and sophisticated embedded systems, offering a compact form factor compatible with breadboards while still providing 14 digital I/O pins, 8 analog inputs, and UART, SPI, and I²C connectivity. The onboard FTDI/ATmega16U2 USB chip translates raw serial USB into a classic 16‑UHS USB‑serial interface, simplifying programming and debugging from any OS.

• Key Spec 1: ATmega328P MCU – 16 MHz, 32 KB flash, 2 KB SRAM, OLED‑compatible I/O
• Key Spec 2: Pin Count – 20 (14 digital PWM, 8 analog) with easy breadboard mating
• Key Spec 3: Power – 5 V USB OR 3.3 V regulator, operating range 1.8–5.5 V
• Common Use Case: Rapid prototyping, robotics, sensor networks, home‑automation loops, and any small‑scale IoT solution requiring a low‑cost, high‑frequency control platform.
