ESP32 Bus Pirate open-source firmware works on off-the-shelf hardware

ESP32 Bus Pirate is an open-source firmware inspired by the original Bus Pirate from Dangerous Prototypes, which turns off-the-shelf (ESP32-S3) hardware into a multi-protocol hacker’s tool. It 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’s been tested on Espressif ESP32-S3-DevKitC-1 development board, M5Stack Cardputer, M5StickC Plus2, Atom S3 Lite, M5Stamp S3, and LILYGO T-Embed (CC1101) boards. ESP32 Bus Pirate firmware highlights: Interactive CLI via USB serial – For faster performance and high responsiveness Web interface (over WiFi) – No cable needed to the host, works from any web browser Supported Modes HiZ (default) – High-Z is a safe mode where all outputs are disabled and all power supplies are turned off I2C (scan, glitch, slave mode, dump) SPI (flash, SD card, slave mode) UART / Half-Duplex UART (bridge, read, write) 1-WIRE (ibutton, temp sensor) 2-WIRE […]
