# ESP32 Bit Pirate\n\n[](https://geo-tp.github.io/ESP32-Bit-Pirate/)\n\n\n**ESP32 Bit Pirate** is open-source firmware that turns your device into a multi-protocol development and analysis tool, inspired by the legendary Bus Pirate.\n\nIt supports sniffing, sending, scripting, and interacting with various digital protocols (I2C, UART, 1-Wire, SPI, etc.) via a serial terminal or web-based CLI. It also communicates with radio protocols like Bluetooth, Wi-Fi, Sub-GHz and RFID.\n\nThe official project website centralizes everything: [ESP32 Bit Pirate Website](https://geo-tp.github.io/ESP32-Bit-Pirate/).\n\nFrom there you can [install the firmware](https://geo-tp.github.io/ESP32-Bit-Pirate/webflasher/), open the [web tools](https://geo-tp.github.io/ESP32-Bit-Pirate/web-tools/), follow [hardware guides](https://geo-tp.github.io/ESP32-Bit-Pirate/hardware/), explore [recipes](https://geo-tp.github.io/ESP32-Bit-Pirate/recipes/), and access the [documentation](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki).\n\n\n\n\n## Features\n\n- Interactive command-line interface (CLI) via **USB Serial or WiFi Web**.\n- **Modes for:**\n   - [HiZ](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/01-HiZ) (default)\n   - [I2C](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/05-I2C) (scan, glitch, slave mode, dump, eeprom)\n   - [SPI](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/06-SPI) (eeprom, flash, sdcard, slave mode)\n   - [UART](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/03-UART) / [Half-Duplex UART](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/04-HDUART) (bridge, read, write)\n   - [1WIRE](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/02-1WIRE) (ibutton, eeprom)\n   - [2WIRE](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/07-2WIRE) (sniff, smartcard) / [3WIRE](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/08-3WIRE) (eeprom)\n   - [DIO](https://github.com/geo-tp/ESP32-Bit-Pirate/wiki/09-DIO) (Digital I/O, read, pullup, set, pwm)\n   - [Infrared](https://github.com/geo-t
