Description

Everything an UNO does, shrunk to a board that plugs straight into a breadboard. Ideal for compact projects, wearables and permanent builds on perfboard. The pin headers come soldered, so it's ready to use out of the box.

Features

ATmega328P at 16 MHz – same chip and code as the UNO R3
14 digital I/O (6 PWM) and 8 analog inputs (two more than the UNO)
CH340 USB-to-serial with a Mini-USB socket
Power from USB, or 7–12 V on the VIN pin
0.6" pin spacing – fits a standard breadboard with free rows on both sides

Getting started

In the Arduino IDE choose Arduino Nano as the board. If the upload fails, set Processor → ATmega328P (Old Bootloader) – many compatible Nanos ship with the older bootloader.
