geo-tp/esp32-bit-pirate

ESP32 Bus Pirate is firmware that turns a small ESP32-based device into a versatile hardware hacking and debugging tool, inspired by the well known original Bus Pirate gadget. Once installed on supported hardware, it lets someone inspect, send, and script commands over many different wired and wireless protocols directly from a terminal window or a web browser based interface. Supported wired protocols include I2C, SPI, UART, 1-Wire, and others common in electronics work, useful for tasks like reading data from an EEPROM chip or debugging communication between two circuit boards. On the wireless side, it can scan, sniff, and interact with Bluetooth, Wi-Fi, sub-gigahertz radio signals, RFID tags, and CAN bus traffic often found in vehicles. It also includes tools for infrared remote control signals, USB device emulation like acting as a keyboard or mouse, and control of addressable LED strips. The firmware runs on several small handheld devices from the M5Stack and LILYGO product lines, as well as plain ESP32-S3 development boards with enough flash storage. Getting started is done through a web-based flashing tool that installs the firmware directly from a browser with no separate software download needed, or through M5Burner for supported M5Stack devices. After flashing, someone connects either over a USB serial cable or by joining the device's own Wi-Fi network and opening its web CLI. Because many of its features, like Wi-Fi deauthentication attacks, Bluetooth spoofing, and RFID cloning, can be used to interfere with networks or devices someone does not own, this kind of tool is intended for authorized security testing, electronics debugging, and hobbyist hardware exploration, not for use against systems without permission. The project has an extensive wiki covering every mode in detail, and a companion repository of ready-made scripts. The current branch described here is deprecated in favor of a newer "pioarduino" branch.
