El Arduino Nano es una placa de desarrollo con microcontrolador compacta basada en la plataforma Arduino. Ofrece un conjunto de pines de E/S digitales, varios pines compatibles con PWM y entradas analógicas, y normalmente se conecta a sensores y módulos mediante sus cabeceras GPIO y las líneas I2C (SDA/SCL). La programación suele hacerse por USB (serie) o mediante ICSP.
