    Why would you need direction control? Pixel data is unidirectional.

    Of course. But it would allow you to build all the boards the same way (with just a jumper), rather than two different assemblies, one each for transmission and reception.

    Why would there be a need for a receiver? This looks like a straight driver chip used in a regeneration mode. same level in and out the only timing change would be a transition latency which would be common to both clock and data.

    I was assuming a differential line driver and receiver.

    No, this is logic level driver.
    However, I do have differential data board that I have created for my floods and that one does have in and out (it actually has 2 pars of inputs and outputs, one diff, one logic level.)

    Do you think there's need for differential driver set?

    Differential Pixel extender already exists. This is simpler (and cheaper)

    What would be the time frame for these from group buy to shipping?

    Well, if I skip test boards, I could ship in 2 weeks, 3 at most.

    I would be in on this as well, what do you need to get it rolling? I would take 2 dozen maybe more, does it work with 5v and 12 v ?
    Help is just a mouse click away

    In simple terms, it can be all one unit. In digital communications it is called a repeater. Input, clean and send.
