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.

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 also communicates with radio protocols like Bluetooth, Wi-Fi, Sub-GHz and RFID.

The official project website centralizes everything: ESP32 Bit Pirate Website.

From there you can install the firmware, open the web tools, follow hardware guides, explore recipes, and access the documentation.
