Arduino (driver signed) is the official digitally signed Windows driver package from Arduino that enables secure, reliable USB detection, programming, and serial communication for supported Arduino boards. It installs the necessary USB-to-serial components so Windows recognizes devices such as the Uno, Mega 2560, Leonardo, Micro, and other official models without warning prompts or manual setup. The digital signature ensures integrity and compatibility on 64-bit systems, making it suitable for managed or enterprise environments. Use it with the Arduino IDE or Arduino CLI to upload sketches, access the Serial Monitor, and perform board maintenance over USB. Note: Some third-party or legacy boards may require separate drivers (for example, FTDI, CH340, or CP210x) from their manufacturers.
Arduino (driver signed) is developed by Arduino. The most popular version of this product among our users is 1.8.
