Product description
Bus Pirate 6 is the latest version of the highly popular open-source hardware debugging tool. Serving as a versatile instrument for troubleshooting and electronics development, it is particularly useful for engineers, hackers, and makers. Bus Pirate 6 is a universal debugging tool designed for analyzing and troubleshooting microcontrollers, sensors, solid state storage devices and other integrated circuits.
The primary function is decoding and debugging serial protocols and other low-level communications. It is also highly useful for reverse engineering, repairs and figuring out electronic devices with poor documentation. Bus Pirate is a complete, compact logic analyzer and completely open source - both hardware and firmware is fully documented. Developed by Dangerous Prototypes.
Version 6 is based on the Raspberry Pi RP2350B, which yields a higher clock frequency, more RAM, enabling a new mode: Follow Along Logic Analyzer. In this, the logic analyzer can trigger anytime Bus Pirate sends a command, with no need for setting triggers. As soon as something happens on the bus, alls samples are sent to the computer (running PulseView). Zooming in and panning, including looking at historical samples are supported.
Functionality:
- Supports UART, I²C, SPI, 1‑Wire, MIDI, and manual bit-banging
- Support for reading and writing to Flash memory, 24x/25x/93x/95x EEPROMs, DDR5 SPD smart cards, and FRAM memory.
- Configurable I/O voltage from 1.65V to 5V
- Command-line terminal via USB serial connection with help functions, data logging, and scriptable interaction
- Powered and programmed via USB; appears as a standard COM port on Windows, macOS, and Linux
Typical use cases:
- Troubleshooting and monitoring serial data buses in embedded systems
- Reverse engineering of protocols and communication analysis
- Firmware development and low-level hardware testing
- As an educational tool for learning digital protocols and electronics
