Breadboard power termination

Hi

What does anyone do to terminate multiple power rails (e.g. 5v, +9v, 0v, -9v) for breadboards ?

I know that there are things like this https://uk.rs-online.com/web/p/breadboards/8352712/, and boards that have 4mm sockets on their baseplates, but they don't seem to add much value.

Thanks

Just stick the wires in directly.

If you are using solderless breadboards you are already in a state of sin, so one more "suboptimality" won't be noticed.

Alternatively consider that every non-soldered connection is a problem waiting to surface, so it is not a good idea to add unnecessary connections.

Have fun debugging your solderless breadboard (with parasitic and varying L,C,R); after that you can move on to debugging your circuit.

I discovered these recently: https://www.ebay.com/itm/3X-MB102-Breadboard-Power-Supply-Module-3-3V-5V-for-Arduino-Bread-Board/222743649206
it plugs into your breadboard and provides either 3.3v or 5v on both sides.


I ordered one. Will be here in a few weeks.

I have quite a few I’d those thanks but I’m referring to multiple rails.

Yes.  Factor in the fact that these are Chinese ones and you get to have even more fun  :)
