Bus Pirate v4 is a universal bus interface that talks to electronics from a computer serial terminal. Get to know a chip without writing code. Eliminates a ton of early prototyping effort with new or unknown chips. Seeed Studio is the official manufacturer and supporter of the Bus Pirate project. Version 4 is the next generation Bus Pirate hardware, but it's not as stable as Bus Pirate v3.


If you're just starting out with the Bus Pirate we still recommend v3 - it's cheaper, more reliable, and has all the same major features. See a Bus Pirate v4 vs v3 comparison. Protocols 1-Wire, I2C, SPI, JTAG, asynchronous serial (UART), MIDI, PC keyboard, HD44780 LCDs, and generic 2- and 3-wire libraries for custom protocols.

    It's all good. I've talked with it using screen program. Self test did not yield any errors. Have not tried to use it with something else yet.

    Bus Pirate v4 Most time i use this for IC interface verification. In these disciplines the bus pirate is without any competition. My second application is very fast T&M tools. In these disciplines he makes my HW complete. Best tool in its class

    Garbage The firmware is incomplete out of the box and development has been abandoned by dangerous prototypes. I'm not talking missing features - rather, this thing is actually broken. The firmware frequently hangs and can only be recovered with a hard reset. If you have time to waste you could try your luck with the community firmware. Get the v3 instead.
