    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.

    • Buffered interface works with 3.3volt to 1.8volt targets

    • Reprogrammable buffer is compatible with multiple debugger types

    • Compatible with 'jtagkey', 'KT-link' programmer settings in OpenOCD, urJTAG, and more

    • ships with JTAGkey compatible buffer image pre-programmed

    • Should support Serial Wire Debug when available

      • CPLD buffer logic overview

      • V4 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

      • Fitted in a DP9056 (90x56 mm) standard PCB

      • Added series resistors to input and output pins to protect against damage and noise
