Product Description

BreadBoard-400 is a solderless (plug-in) breadboard with 400 connection tie-points (i.e. 400 wire insertion holes). It has 4 power rails.Solderless breadboards are great for building and testing new circuits because parts can be easily inserted and removed. They are completely re-usable. The BB400 has a 300 tie-point IC-circuit area plus four 25 tie-point power rails. The housing is made of white ABS plastic, with a printed legend giving numbers and letters for columns and rows. The internal contacts are phosphor bronze with a plated nickel finish.A peelable adhesive tape backing is provided for attaching it to a surface.BPS BreadBoards are Lead-Free and RoHS Compliant. Finished projects can be moved to a SB400 Solderable PC BreadBoard to make them permanent.

Everyone else has mentioned the key points. It's a BreadBoard. The last line of the right up does mention "Peelable adhesive tape backing provided for attaching to a surface."

Here is what isn't mentioned. This thing is designed to be snapped together. You can take the power rails off of one side and add them to the other or remove them all together. If you buy more than one of these you can snap them together to make a much larger BreadBoard.

Last point, there is a companion SB400, that is a single sided PC board that has the exact same layout as the BB400, so once you have a working design, you can transfer it right over to a PCB to solder finalize.

All in all I'm impressed with the thought that was put into this simple product.

This is a breadboard. It's very simple yet incredibly helpful in prototyping circuits before committing to a permanent solder job. HOWEVER, this particular model can be ruined if you use the seemingly great adhesive bottom. All of the contacts are held in by the adhesive layer. I had this stuck to a project to keep the wiring stable, but when attempting to remove this product the adhesive layer tore off in chunks, taking the innards with it.

Needless to say, I'll be replacing it with something much more durable and well-designed.

If you buy this (the price isn't bad at all), just don't stick it to anything!

This is a good breadboard.

My only problem:
I purchased this BB400 and the larger BB830 together. I assumed they would fit together with their tongue and groove system. This is incorrect.
The BB400 has smaller joints than the BB830 (which makes sense, now).

It was my fault for not taking a closer look at the pictures.

Bought a couple to create modular systems for the design of a device I have been working on for about a year. The connections all seemed to be snug and I had no issues with loose or ill conected components. Using the modular design concept allowed me to substitute different a module and immediately evaluate the overall changes in the device and also allowed me to return to a previous set up with a minimum amount of fuss. I would buy several if you are working with digital or analog systems just for the convenience alone.

The item worked nicely as a breadboard, but on the bottom you can see double sided tape. I expected to be able to tape it to a project then move it later and put some more double sided tape on it. But when i removed it from the first project I realized that the tape actually keeps the breadboard connection on the bottom pressed in. So once you stick it with the double sided tape, don't expect to ever be able to reuse this breadboard. Either don't use the double sided tape on it. Or use it once and trash it.

I would give this five stars if the design was such that the edge power rails matched in alignment and distance to the center board.
I don't understand this concept of misalignment. It forces one to use different parts than desired when designing a circuit in order to fit the alignment and the parts don't sit nice and straight. It does not really match the SB400 Solderable PC BreadBoard, which, does not make any sense either. Otherwise ok.

This is an excellent little breadboard. One thing not mentioned in the details is the power rails can snap off and you can also snap multiple BB400s together to make a bigger breadboard. The back also has a double-sided sticky pad attached so you could adhere it to a flat surface.

You can also get a corresponding product, the SB400 which is a solderable board that matches the BB400. Once you have your project tested and working on the breadboard, you can move it over to the solder board and make it permanent.

I've already picked up a few more so I can keep multiple circuit ideas going at once, or combine them to mockup bigger circuits.

Been using mine for about 8 months. It's defect free and has been functioning perfectly. I like the build quality of this product, especially considering it's real low price.

It's great for small quick projects, and when I need to use one off-site. For home use I think a larger board might be more convenient to use; it gets a little crowded quick when the projects become more complex.
