## Description

Experience the GENUINE Difference - BusBoard's BB830 and BB400 BreadBoards are now branded to help ensure you know you are getting the quality, precision, and reliability you expect. Look for the BB400 Part #, black and red power rail indicators, and horizontal legend orientation.BB400 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.

Review: Good sturdy connections and conductivity - Sturdy and worked as described
Review: 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.

### ⭐⭐⭐⭐⭐ best breadboar I've found. Option to snap several together is freakishly useful!
*by A***T on November 4, 2013*

I ordered a basic breakout kit, then followed that order up with several of these breadboards. These ones are far superior in most every way conceivable. As stated in the description, you can snap several of these together, either side by side, or end to end. The power strips on either side are removable & can be repositioned as well to fit your size needs. The breadboard itself feels fairly heavy & sturdy for what it is. Does not feel like many of the other cheap/low end Chinese products out there. I can't even mark it as a negative because of the functionality, but the side power bands do seem like they come off the unit a little too easily. After I finalize some sort of case design, i'll be gluing them together. In the meantime, the adhesive backing does a good job of keeping everything intact as it is not scored or perforated (read: knife required if you want to remove/move the power bands around). Having both + & - lines on either side really helps clean up the wiring, and definitely makes drafting the schematics a little easier. All in all, this seems to be the best breadboard I've come across. I'm happy I ordered 4 of them, and I'm fairly confident I'll be looking for this one again when/if I ever need more of them. **mentioned above another generic ordered, this is the link to it. Bonus for this kit is it includes all the other goodies. Crash Your Pi !
