@ taylorza - This is cool stuff dude. Thanks for sharing, and thanks for explaining.
My problem with understanding the DL40 module is the fact that it only has two sockets. I need a socket to connect backwards, and one to connect forward in the chain, and then one for the module that I need on the chain.[/quote]
You could wire the DL40 headers to one (or more) of these:
I guess it would depend on what you need — perhaps this would be more appropriate:
Currently, you need to provide the circuitry for that.
Based on Ian’s suggestion, it would be a function of the mainboard . I’m guessing the mainboard could connect/disconnect the ground to the socket.
