    Sadly obsolete :-( Excellent quality design and manufacture, but sadly this version is now obsolete, there are better solutions out there with far larger capture buffers.

    What were they thinking ? I am still waiting for a wing board. what were the designers thinking when they thought they would save a few pence on a buffer so the end user has to obtain that, some connectors then assemble it into something sensible that doesn't fall apart ?

    Some important signals are only available in the middle of the board.

    Sadly useless I had hoped this would work but I can't get it to be useful at all.
    The hardware appears OK but the software is worthless.
    There are 3 programs that are supposed to work with this:
    1) SUMP - supposedly designed for this board. Has not been worked on since 2008. Needs RXTX that is not compatable with x64 systems. Replacements for RXTX not known to work.
    2) sigrok's PulseView - frequently gives "generic unspecified error" - anyone who writes code that generates messages like that should give up programming.
    3) Open Bench Logic sniffer version 3.08 - ish-works but few decoders. Even then, the sample time is uselessly small.
    I strongly caution against buying this unless you can be sure of finding functional software for it.
