Soldering the Bus Pirate v4

Watch us solder the Bus Pirate v4.

The Bus Pirate is an open source hacker multi-tool that talks to electronic stuff. For a comprehensive overview check out our previous post.

Here are the main differences and advantages of V4 over V3:

  • Integrated USB in the microcontroller (faster)
  • Data storage EEPROM to hold settings
  • Pull-up voltage selections: 3.3volt, 5volt, or external supply
  • 2 extra I/O pins
  • Multipurpose button
  • Bus Pirate v4 vs v3 comparison

The Bus Pirate V4 is still a work in progress. If you want a reliable and fully tested tool, we still recommend the v3.  It is actively developed and will be manufactured for the foreseeable future. Development on the V4 will continue, and we will let you know when we think it is the go-to hardware.

You can get a Bus Pirate v4 for $40, including worldwide shipping.

    1. Maybe… We don’t currently have them in the PCB store, but we could. We could also put them as Seeed I guess.

  1. Hello,

    I’d like to learn this soldering technique.
    Do you use hot air tool?
    What kind of equipment and materials do you use?
    Is this lead free?


  2. Ian doesn’t like soldering fumes, so he uses a fume extractor attached to his soldering iron, its the strange looking tube that goes parallel to the iron…
    BTW, in this video he explains the equipment used as well, disregard the first part when he uses hot air to remove the IC.
