I got it working numerous times but then I'd ever so slightly bump the thing or begin to add more components and then my data would stop showing up on my LCD (SunFounder LCD2004 Module with 3.3V Backlight for Arduino Uno R3 Mega2560 Raspberry Pi Display of 20x4 White Characters on Blue Background ).
It was quite terrible. I couldn't figure out what was going on. Then I started testing continuity (with my multimeter).
I noticed that I didn't have continuity from LCD connection down to the bread board. Next I tested continuity just on each wire.
There is literally no continuity from one end of (many) these wires to the other. That was shocking. Then I started testing them as I bent them.
As I would move them the wires would lose continuity meaning that somewhere in the wire there was a break.
Well, the way these jumpers work is that they are a wire that is crimped into a pin on each end -- these are the pins that help you push the wires into the bread board.
BEWARE THE WIRES!
The connection from the actual wire into the crimped on pin is not good so that if you even slightly move them then you get no connection.
I had about 5 or 6 red ones and for some reason I found that 5 of the 6 red ones were bad.
Not sure if that is just coincidence or what. Anyways, as the day went on and I used these I basically found that the connection from wire to that pin would become loose. It could be from pulling them out of the bread board or whatever.
The terrible thing is that intermittently one wire or another would go bad and that made things really difficult.
It's not even worth trying to use these wires at all because you get false positive success and then it fails later.
Now, I thought the boards were okay, but now I've read some other reviews and they seem to indicate similar things with the boards.
The thing is if your boards or wires are not at least 95% good then you are going to get errors and problems that are related to things that you don't expect and it's going to make your work extremely difficult. I know it did in my case.
I'll look elsewhere for boards and now I won't trust these jumper wires but will instead move to solid core wire from now on.
The spacing between the two central rows (where you put an IC) seemed out of spec.
The GPIO to breadboard converter from CanaKit would not fit this breadboard. It worked fine on every other breadboard. However, on this one the spacing between the middle rows was too great. I was, however, able to fit seven segment LEDs on the middle rows. I did not try other ICs, but you could likely make them fit. However, I think I would just buy a different breadboard that had proper spacing.
Overall, a great little breadboard that's easy to use and modify.
