Bus Blaster v4 is an experimental, high-speed JTAG debugger from Dangerous Prototypes.

Thanks to a reprogrammable buffer, a simple update over USB makes Bus Blaster compatible with many different JTAG debugger types in the most popular open source software.

  • • ŸBased on FT2232H with high-speed USB 2.0
  • • ŸBuffered interface works with 3.3volt to 1.8volt targets
  • • ŸReprogrammable buffer is compatible with multiple debugger types
  • • ŸCompatible with 'jtagkey', 'KT-link' programmer settings in OpenOCD, urJTAG, and more
  • • Ÿships with JTAGkey compatible buffer image pre-programmed
  • • ŸShould support Serial Wire Debug when available
  • • ŸMini-CPLD development board: self programmable, extra CPLD pins to header
  • • ŸOpen source (CC-BY-SA)

      Updates in v4:

      • • ŸV4 uses a larger CPLD than previous versions. It can now support the SWV feature of Cortex microcontroller for advance debugging when software support is available
      • • ŸSWV is little used and not currently supported in software, most users will be better off with Bus Blaster v3 available here
      • • ŸFitted in a DP9056 (90x56 mm) standard PCB
      • • ŸAdded series resistors to input and output pins to protect against damage and noise

      Each unit is tested before it ships.

★★★★★ Great bag
Purchased this for my 23 year old daughter in the butterscotch color. Great versatile color. She loves the size -- perfect for day or going out at night. Chain can be double to shorten for nighttime and left long to wear as a crossbody during the day.
