The Arduino Micro is a compact, open-source microcontroller board based on the ATmega32U4 chip. It is designed for easy integration into small-scale projects and prototypes, especially where space is limited. The board features multiple digital and analog input/output pins, USB connectivity, and can be programmed using the Arduino IDE. In cybersecurity, the Arduino Micro can be used to simulate USB devices, automate tasks, or test hardware security. Its versatility and ease of use make it popular among hobbyists, educators, and professionals for building interactive electronic devices, including those used in penetration testing or security research.
