Bus Pirate 5 is the latest edition of the original universal serial interface trusted by hackers since 2008. We've stocked and loved the Bus Pirate 4 for years and are excited to see the latest and greatest from the minds at WhereLabs.

Can't get a chip to work? Is it the circuit, code, bad part, or a burned out pin? The Bus Pirate sends commands over common serial protocols so you can get to know a chip before prototyping. Updated with tons of new features and tools, talking to chips and probing interfaces is more fun than ever!

The Bus Pirate is an open-source hardware debugging tool that converts simple commands into common bus protocols such as 1-Wire, I2C, SPI, UART, several LEDs and more. Send commands to a chip or sensor and get the response, without writing a line of code.

Commands are entered into a serial terminal. A new VT100 mode supports color text and a status toolbar that displays the function and voltage of each pin.

Specs:

The Bus Pirate is designed to eliminate the frustrating parts of hacking and hardware tinkering. We tried to tackle all the pain points, from bizarre and uncomfortable acrobatics with multimeter probes to the hassle of connecting multiple test hooks to a single pin. With Bus Pirate 5, information you need is right where you need it.
