## What it is
An Arduino library that adds enhanced USB HID functionality to standard Arduino boards, enabling them to act as keyboards, mice, gamepads, and other HID devices. It supports a wide range of AVR and SAMD boards, including via HoodLoader2, and offers features like NKRO keyboards, consumer/media keys, and RawHID.

## Use cases
- make an Arduino act as a keyboard or mouse
- send media keys from a microcontroller
- build a custom USB gamepad with Arduino
- emulate an NKRO keyboard on a Leonardo or Pro Micro
- send raw HID reports to a PC from Arduino
- add a Surface Dial emulator to a project

## When to choose
- you need advanced HID device emulation on Arduino boards like Leonardo, Micro, or Uno with HoodLoader2
- you want NKRO keyboard, gamepad, or consumer key support beyond the stock Arduino Keyboard/Mouse libraries
- you need boot protocol keyboard/mouse support for BIOS compatibility

## When to avoid
- your board is an Arduino Due (ATSAM3 is unsupported)
- you need USB host functionality rather than device emulation
- you are not working with Arduino-compatible hardware

## Facets
- artifact type: library
- maturity: stable
- function: embedded, sdk, developer-tools
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, iot, cpp, c
- tags: arduino, hid, usb, keyboard, mouse, gamepad, rawhid
