    Funnily enough, just received an aluminium sheet to bolt both the Pecan dac and the Allo sig to.
    I was just looking at it thinking I might as well get a cheap Chinese case and put them both in.

    Cool, I’m interested in your gpio cable, I’ve not fitted mine as I wasn’t sure which way round to have it, I see the red edge going to the Pecan so that helps me, which way is the Pi facing within the Allo bridge?

    Hi Mike.
    I’ve already zapped an old raspberry pi by getting the gpio cable the wrong way ... so it pays to be careful!!
    The Pecan would sit as it looks in the photo. So that the 40 pin connectors would clip together with the underside of the Pecan dropping down into the pi.
    So when you get the cable it’s useful to look at the red strip at one end and make sure you have both ends where they should be.
    Am I making sense? Possibly not, but it is very straightforward when you get the cable and you can visualise how it is just an extension of how the dac would sit onto the pi.

    By the way the Pecan Pi is fantastic when married to the Allo USbridgre and linear power to both the pi and dac. Not cheap, but I am very impressed with what Orchard have done with a humble HAT.
    Good luck !

    Sorry Mike
    To answer your question the pi sits with the 40 pin connector on top and I’ll lift the lid and take a pic

    Of course the Allo Sig USbridge is not a pi, it just uses the core. However the principle is the same.
