Not blaming!! Suggesting improvements - but you probably don't see these suggestions as "improvements". I have reacted to your requests for improvements, because they made sense to me. I don't understand why it is such a big deal. If you don't like LambdaBoard and consider it a "clone" of MotherX4, then you could improve MotherX4 such that I could use it with DDI3, then I wouldn't have to make my own solution. That means, you could add an edge connector directly to the end, and/or make the diode and PSU optional. I don't want an extra PSU to power it if it is known to be unnecessary. So, you either have to live with the fact that people create their own "solution" with their lego electronics understanding, or provide something that would address their problem. IMHO. Anyhow. Best wishes, get well!
