    To run the 7 inch LCD you don’t need the new Beaglebone Black – the older original Beaglebone will do fine. There may even be a few original ‘bones on sale now the new Black has been released.

    Is there anything specific to this that requires the Black version?

      wasnt original beagle 2-3x more expensive than black?

      • Alan says:

        It was about $20 – $30 more depending where you live [postage & freight]. The new BBB is cheaper. I’d just like to find a valid, permanent setup that doesn’t need all the extras of the BBB, and give a old board a home.

    Man, $150 bucks for this 7″ LCD Beagle cape? Wow!

  4. Alan says:

    Yeah, $150 for an LCD. Pop Quiz:

    Someone has a Kindle / Nook / Whatever clone. You can take off the backing plate, and beside replacing the battery you ALSO have access to Beaglebone-style expansion headers. All you need is a different backing plate, to house any custom board you choose to add.

    Do you buy it – or insist everything be 2mm thick, Apple-knockoff style?

    What software are you using to write the HMI?
