# Flipper Zero ## Theory The Flipper Zero is a versatile, portable, open-source multi-tool designed for pentesters, security researchers, and hardware enthusiasts. It specializes in wireless communication hacking (like RFID, NFC, and sub-GHz signals) and can also interact with various hardware interfaces such as GPIO, SPI, I2C, and UART. The Flipper Zero is small, user-friendly, and includes a variety of tools for interacting with and manipulating various types of embedded devices and wireless systems. ## Key Features * RFID and NFC * Reads and emulates RFID and NFC cards, making it useful for proximity-based systems. * Sub-GHz Transmitter * Transmits and receives signals in the sub-GHz range, useful for wireless key fobs and smart home devices. * Infrared (IR): * Emulates infrared signals for controlling IR-based devices. * GPIO, SPI, I2C, UART * Provides a physical interface for working with embedded hardware, ideal for debugging, flashing chips, and communication testing. * Modular and Open Source * The community actively develops firmware, making it highly customizable. ## Resources \*[Flipper Zero](https://flipperzero.one/) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
