First of all, I don't know the question category, so I'm asking here. please understand.
I would like to connect the Arduino board and other boards to the inner plate of the distribution box.
If you know how, please let me know.
I also want to keep the lines connecting the boards clean.
Is there something like a connection jack? Or do I have to solder it?
I would appreciate it if you could tell me how to connect the boards and organize the lines.
The current connection status is as shown in the photo below.
