Micro SS is an ATmeag32U4-based microcontroller board. It has 14 general-purpose digital input/output pins. onboard oscillators at 16 MHz and a USB-A PCB-based connector In addition to an independent power supply to 3.3 V output, its output power depends on the USB power capability but is limited to a maximum of 1.5A without affecting MCU operation. the council was recording Ard Arduino bootloader, so it is compatible with the Arduino IDE. Although it is small, it has a rich interface that includes not only the traditional controller functions, but also the computer mouse, keyboard functions, a series of functions, and the ability to communicate directly with the computer.

BadUSB is a dangerous USB security flaw that allows attackers to turn a simple USB device into a keyboard, which can then be used to type malicious commands into the victim's computer.
How it works
BadUSB revolves around the fact that many different devices plug into the same USB connectors. By hacking the code of the USB microcontroller of an "innocent" device, like a USB memory stick, you can turn it into something far more capable, such as a keyboard or a
network card. Stick the device into a computer and it could execute commands or even a malicious program without the owner knowing. Stick the device into a computer and it could execute commands or even a malicious program without the owner knowing.
