Take a look at the codebase or just try it out, and make up your own mind
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.
Turn a $5 ESP32-S3 into a browser-based hardware workbench.The Bit Pirate firmware is complemented by scripting, hardware dock, extension, adapters, browser tools, documentation and practical embedded workflows to enable comprehensive hardware debugging and development with serial interfaces or Wi-Fi connectivity.
Designed to work especially well with ESP32 Bit Pirate: https://github.com/geo-tp/ESP32-Bit-Pirate
It supports voltages from 1.8 V to 5 V when used with the dock
If you want, you can push the platformio env for your specific board to add it to the list of supported boards
You do not need to connect a separate USB-UART adapter to it: simply connect the ESP32S3 UART pins directly to the board’s TX, RX, and GND pins.
Any ESP32S3 board could do it, see README for different types of supported devices
I know the codebase inside and out, feel free to ask
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.
So it is not simply a cheaper Bus Pirate v6 clone
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.
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.
