24 customers mention "Size"16 positive8 negative

Customers have mixed opinions about the size. Some find it fits well and is the right size, like a 4WD Robot Chassis or T-Shape Raspberry Pi Cobbler. Others say it's small and not full-size breadboard, but works for their needs.

"...diodes, capacitors, resistors, and 0.1" header pins inserted smoothly into this breadboard, and the connections are solid and reliable...." Read more

"...the a-e shared the same pin connection as f-i, because the width is already very narrow. Just a personal preference. Not a big deal...." Read more

"...It is a decent size...." Read more

"...admittedly cost a bit more, but which are also an easy fit for all the same components." Read more

    5.0 out of 5 stars High quality, reliable breadboard

    BB400 Breadboard
    All TO-92 transistors, ICs, diodes, capacitors, resistors, and 0.1" header pins inserted smoothly into this breadboard, and the connections are solid and reliable. I was especially impressed that my metal film resistors (with ridiculous hair-thin leads) made reliable contacts. On my old cheap same-size, no-name breadboard, it became a nightmare when the thin leaded resistors made intermittent contacts. I ended up having to shove in a header pin in the same hole with each resistor lead to get a reliable contacts. Also, I had to work almost every hole with a safety pin in order to enlarge the hole, and line up board's contacts for the heavier leaded components and jumper wires. I didn't have to do any of this on this breadboard. So far it's been working perfect. I have not had a one intermittent connection issue.

    Finally, make sure the breadboard you buy has "BusBoard.com" printed on the edge along with the model number "BB400" like on this breadboard. I won't buy a no-name brand breadboard ever again.
    I highly recommend this board from BusBoard Prototype Systems.

    Reviewed in the United States on December 7, 2011

    First of all, I would like to start by saying that this is my first breadboard purchase. I'm just getting into electronics as a hobby, and I needed something to start with. Wow, was I blown away! This breadboard is incredible. It does pretty much everything that I would require a breadboard to do, including conducting electricity and holding components in place. It really shines in those two respects. If you want something that not only conducts electricity, but also holds the components in place, YOU NEED THIS BREADBOARD!

    I know what you're thinking right now. "Well, I want to buy it.. and I'd really like to have a breadboard.. but I don't know if I should spend my money on this or a McDonald's value meal." Wonder no more, you have to buy this thing. You don't need to eat, but you do need to build epic electrical circuits and get your prototyping game up in preparation for a robot invasion. Ditch McDonald's and get an awesome breadboard (like this one (preferably this one)).

    I was so stoked when I received this package in the mail. I immediately took it inside and opened the box. I was greeted with a piece of paper taped to what looked like a bag that marijuana would be kept in. But there was no marijuana, as the breadboard inside was simply too awesome to be roommates with any controlled substance. So I removed the breadboard and slapped it up on the ole' desk. "Finally," I thought, "it is here!" Without thinking twice, I whipped out the Fluke multimeter and started to test the tie points. "TROLLED LOL," is the response I was greeted with, as I have no proper breadboard leads for my multimeter. Well played, you sly device.

    My only complaint is that the package didn't include the wallet full of cash to buy more breadboards. I'm really sure that was in the description. Oh gee, Amazon, false advertise much?

    On second thought, I may have read the wallet thing in a Lost & Found ad on craigslist. You win this round, Amazon.

    Reviewed in the United States on March 17, 2013

    It is a bread board. Not much to say about it, these things are fairly basic.

    I like the color-coded rails, makes it easy to see at a glance where to plug in without tracing wires. It is a decent size. It is hard to see in the picture, but there are tabs on all four sides so if you have multiples of these you can snap them together into a larger board.

    The power rails on the sides also detach from the main part of the breadboard. At first I thought it was flimsy plastic construction, turns out to be the snapping thing combined with the adhesive backing keeping it together.

    The only thing this is missing is a dedicated power connector. Some boards have screw-down terminals for easy and secure power connections. Given the modular nature of this board that is not feasible and I really can't say it's a bad thing not to have it. This board is easy enough to power and works great.

    BBS BREADBOARDS CONSISTENTLY MAKE BETTER CONNECTION WITH A WIRE THAN OTHER BREADBOARDS I HAVE USED. WHEN A WIRE IS INSERTED INTO A CONNECTION POINT THERE IS LITTLE OR NO SLOP WITH THE CONNECTION. GOOD BOARDS.

    4.0 out of 5 stars Good item, not reusable
    Reviewed in the United States on June 29, 2012
    Verified Purchase
    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.

    Hands down this is the best quality breadboard available. Worth the premium price. Marketings are clear and crisp. Wire insertion and holding force are uniform, firm and durable. Perfect for 22 g solid wire. I have tried numerous other brands and this is the only one I purchase now.

    3.0 out of 5 stars small holes
    Reviewed in the United States on March 5, 2015
    Verified Purchase
    These are good if (1) you like the modularity (not a bad feature) and (2) you don't mind the small holes. All of my components have to be kind of negotiated ("pushed pretty hard") onto these boards. Contrast that with the ones that I buy from allelectronics(dot)com, which, admittedly cost a bit more, but which are also an easy fit for all the same components.
