Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality of the Arduino Due but in a different package. It lacks only a DC power jack and works with a Mini-B USB cable instead of a standard one. It is one of the smallest and yet most exciting breadboard-friendly boards available on the market today. It's become exceptionally popular with beginner programmers thanks to its excellent functionality and the sheer variation of potential applications. Based on the ATmega328P, this tool is fantastic for those who wish to improve their programming skills and create some interesting and unusual projects. While the item does not come with a DC power pack, it benefits from a mini-USB cable for power, and that means you can use it with any PC or laptop device.
Pin Configuration
| D0 (Rx) & D1 (Tx) | Used to receive and transmit TTL serial data |
| D2 & D3 | These pins can be configured to trigger an interrupt on a low value, a rising or falling edge, or a change in value |
| D3, D5, D6, D9, D10, D11 | Provide 8-bit PWM output with the analogWrite() function |
| D11 (MOSI), D12 (MISO) & D13 (SCK) | These pins support SPI communication |
| A4 (SDA) & A5 (SCL) | Support I2C (TWI) communication using the Wire library |
| AREF | Reference voltage for the analog inputs |
| Reset | Bring this line LOW to reset the microcontroller |
