Here are the planned component connections, breadboard-style via Fritzing:

The kit and turnkey versions will both use a custom PCB to make adding or removing components much more straightforward: I’m planning to use lines of headers, placing needed connections in a neat row, while maintaining functionality of the existing pins.
