    • 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

    Updates in v4:

    Each unit is tested before it ships.
