Q. Will these boards clip together with other K&H Boards? Specifically the 34-0668 Power Block or the 34-0662 AD11.
A. Hi John, thank you for your question. We have physically tried the 3 parts and they are not compatible directly. However multiple 34-0655 can be connected together. 34-0662 comprises the power block fitted to a breadboard of differing dimensions.
Q. Are these non-magnetic?
A. Hi Nick. Thank you for your question. These PCB prototyping boards are non magnetic.
Q. What's the dimension of this board? Is it 16.5 x 5.5cm?
A. Hi loogmaengaw. Thank you for your question. The protobloc 2 breadboard is 171 x 64mm.
This helped a lot as I experimented in getting the right resistance and configuration. I needed to fit the components into a tight space so this was great for trial and error
I've been using these for many years without issue and have around 200 of them.
In most cases... If you look at most schematics, about half of the components have a connection to rail. Therefore these ones with 2 rails next to every row of uncommitted contacts is going to be the best to use. For the money its acceptable to consider them as single-use breadboards, cheap compared to any other prototyping means. However, they are totally re-useable. I wouldn't expect any of these types of breadboards to be reliable forever, none have gold-flashed contact surfaces, but that's the point isn't it - they're a quick breadboard to get you started.
The quality is fine, and for the price the product works very well.
