There is a built-in LED connected to digital pin 13. These pins support SPI communication, which, although provided by the underlying hardware, is not currently included in the Arduino language. Provide 8-bit PWM output with the analogWrite() function. See the attachInterrupt() function for details.

These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value. These pins are connected to the corresponding pins of the FTDI USB-to-TTL Serial chip. Used to receive (RX) and transmit (TX) TTL serial data. In addition, some pins have specialized functions:

Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. Input and OutputĮach of the 14 digital pins on the Nano can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions. The ATmega328 has 2 KB of SRAM and 1 KB of EEPROM. The ATmega328 has 32 KB, (also with 2 KB used for the bootloader. The power source is automatically selected to the highest voltage source. The Arduino Nano can be powered via the Mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). You can find here your board warranty information. Need any help with your board please get in touch with the official Arduino User Support as explained in our Contact Us page. Need Help?Ĭheck the Arduino Forum for questions about the Arduino Language, or how to make your own Projects with Arduino. You can find in the Getting Started with Arduino Nano section all the information you need to configure your board, use the Arduino Software (IDE), and start tinkering with coding and electronics.įrom the Tutorials section you can find examples from libraries and built-in sketches as well other useful information to expand your knowledge of the Arduino hardware and software. If you are looking for a Nano board with similar functionality but also provide additional features, check:įind inspiration for your projects with the Nano board from our tutorial platform Project Hub. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328 (Arduino Nano 3.x).
