ESP32 Bit Pirate transforms an ESP32S3 into USB hardware tools compatible with applications such as flashrom, PulseView, AVRDUDE, OpenOCD, LIRC and more
Where do you see 600k commits? Are you talking about 600k lines of code? If so, the project includes libraries in the `lib` folder, notably a large screen library called `tft_espi` which must be 500k lines on its own (which has since been removed, that's why you see -500k lines)
I know the codebase inside and out, feel free to ask
The two projects have fairly different directions, even though they overlap on most core wired protocol features.
The original Bus Pirate relies heavily on a more complex bytecode-style syntax for many lowlevel operations. The ESP32 version replaces most of that with simple, explicit commands that perform the same tasks through a more straightforward workflow
The ESP32 version also avoids flag heavy commands and uses interactive shells where appropriate. Its main additional strength is radio support not present on the original Bus Pirate, including WiFi, RFID/NFC, SubGHz, NRF24, FM, infrared, and Bluetooth.
It can also be controlled through the Web CLI from any phone, tablet, or device with a web browser, using integrated AI assistant to help with hardware task.
Yes, it includes scripting and raw GPIO/bit-banging features, so you can read essentially any custom protocol yourself, including one you invented five minutes ago
The implementation is entirely new and was built specifically for this project, it is not copied from another project. LLMs were used as development tools, but the architecture, feature selection, integration, testing, and overall direction were designed and validated by contributors and me.
ESP32 Bit Pirate is an open-source firmware that transforms compatible devices into versatile multi-protocol hacking tools, inspired by the original Bus Pirate.
It can sniff, send, script, and interact with digital protocols such as I2C, UART, SPI, and 1-Wire through either a Serial CLI or a Web CLI. It also supports wireless technologies including Bluetooth, Wi-Fi, Sub-GHz, and RFID.
Install the firmware in one click with the ESP32 Bit Pirate Web Flasher. The Wiki provides detailed guides for every mode and command, while ESP32 Bit Pirate Scripts offers a collection of ready-to-use examples and utilities.
For additional hardware capabilities, the ESP32 Bus Expander adds extra radio interfaces, while the ESP32 Bit Pirate Dock provides compatibility with original Bus Pirate adapters and accessories.
