There are several threads here dealing with the best way to connect several wires to one pin. I believe that a good idea would be a shorter connector with a cable that leaves the connector sidewards. With such a design several connectors could be slid over a single pin. A short online research did not give me any results that such connectors or cables are available - however I can hardly believe that because I do not see any disadvantages of that design.
My questions:
Do you know of a vendor of cables of that design?
Which supplier is suitable to put that design into practice?
Attached images: standard female Dupont connector, very rough sketch of two connectors with sideward cables on one pin
Dupont connectors that stack banana-plug style is an interesting idea, never seen it though, perhaps
its too small and fiddly to be reliable (wirewrap pins are long and square too, perhaps something exists
for those that isn't a wrapped wire?)
I did another search with the proposed search terms but still cannot find such cables.
Wawa:
Just use a breadboard for prototyping, like everybody else does.
I know that this is the common way. However, this is only a good solution if you have plenty of space. I already need to pack an Arduino, a shield, a TFT screen and a battery into a hand-held casing. There is no space for a breadboard.
Handheld is not suitable for breadboard or stacked connectors. If you drop it and something comes unplugged inside then you are screwed.
It's time to learn to solder. Use rows-of-holes protoboard (also available in shields) or design your own PCB in Eagle or KiCad. The quality of PCB you can get for $5 is incredible.
