Electronic – What edge connector for prototype board

connectormotherboardprototyping

For personal hobby projects I'm using prototype boards like this (2.54 mm pitch):

I connect them using wires, which is a mess. I want to use a backplane with female edge connectors, for a solution like this:

Making a PCB is out of question, mostly because I keep adding components to my projects to add further functionalities.

After searching, the only female edge connector I found was 3.96mm pitch ones, that seems to be incompatible with prototype boards.

I'm looking for a solution, better if it accepts the prototype board as is (without a male connector). Cost is not a big factor.

Any sugestion is welcome.

Edit

Durability is not an issue; I keep producing new versions every 12 to 18 months. Cheap components, hardware is totally disposable (I don't even bother recycling them).

Best Answer

If you are not averse to cutting down the PCB and chamfering the raw edges slightly* then something like an ordinary PCB edge connector could work with ordinary Veroboard as the backplane PCB for single-sided daughter boards.

* Remember it's fibreglass so don't get the little shards on your skin or in your lungs if you can avoid it.
