Protoboard Jumpers?

[box1gosrgo]

What is the purpose of the jumper usage on the Protoboard? I just built it and the individual pins have the correct voltages. Why would I jumper them? If I do, how the heck would I use these pins/voltage?

They're there for convenience when breadboarding. You're not supposed to jumper them together....

Use the female end jumper wire to connect a specific rail to the breadboard. For instance for the 9V. You would use a jumper wire from there to add 9V to the breadboard 9V rail. Does this make sense?

I have a protoboard to build, but I haven't started on it yet. I was initially confused by those pins as well.

My assumption is that they're for use with these type female-male jumpers.

You can also use female headers if you'd rather be able to use male-to-male jumpers.

I've used those wires before. They work, but are too long for my taste when hooking up to the protoboard pins. I now use ones from Tayda with really no problems. They're cheap and come in a big pack, so if one breaks once in a while, no big deal.

Also, those "extra" pins on the side are for convenience. For example, you may want 2 rails to be 9V, one rail to be 18V, and a third rail to be -9V. Those extra pins there make is possible without jumpers stretching vertically across breadboards.

this is exactly what I plan to do. the photo doesn't make sense. the jumper makes the voltage covered up and unusable. thanks

Good call.

I'll throw some of these on my next order

The jumpers were from the first revision of the ProtoBoard.

There were conductive tracks under the breadboards that made contact with the power buses, no wires needed, just set the voltage with jumpers on the pin headers.

Unfortunately the connection wasn't extremely reliable so that idea was scrapped.

I need to update those pictures.

ok, that makes sense. I also saw that the dip switch was removed. I just built it this morning- the board is great. can't wait to lay out a circuit this afternoon.

Yup. I completely misunderstood your question/ photo.

I didn't realize the rectangles over the pin pairs were jumpers
