ELEGOO 3pcs Breadboard 830 Point Solderless Prototype PCB Board Kit for Arduino Proto Shield Distribution Connecting Blocks

I like the look and feel of these boards. I have a number of boards from different manufacturers and these are easier to read imo. The boards themselves feel better constructed than the others I have. And I have enough of the half-size breadboards and wanted three full size - Elegoo fit the bill and they are a very reasonable cost. Perfect size for my projects that need the full length (for instance if you want to use a BreadVolt to power the circuit using batteries).

Pretty good but had some problems getting pins to stay in for some reason.

This is a surprisingly tough breadboard. I accidentally blew up a small transformer while it was connected, and even though it left a few scorch marks, the breadboard still worked perfectly afterward. The internal connections remained solid, and I was able to continue prototyping without any issues. Definitely a well-made and reliable product—great value for anyone working with electronics.

This is the best breadboard I have right now. I use it over the other 3 types I previously had. This has nice springs and holds all sizes of wire. Be sure you just angle your pins inward slightly or small breadboard pins can hang up on edges. After a couple attempts and looking at it though, it was easy to tell to just angle the in pins when inserting them correctly. Thanks for this purchase and good price. However their Elegoo 37 Sensor module package stay clear of it if you are new or learning because I bought it for my son and the directions are all wrong and the .pdf included shows you hooking up to channel 12 and you should be on 9. The first project in it doesn't work because he didn't "define his variable". It is a sad attempt and I think he just copied most his code from the internet and used others to make a poorly translated not very helpful CD. It acts like you are going to learn all this from it and you aren't. He doesn't tell you about what is on the boards or the resistors used or anything. I am waiting for him to contact me back and see what he wants to do about this if anything before I send it back.

3 Fully sized breadboards. High quality for price. Breadboards have attachment points at the sides to connect to other breadboards to assemble a bigger breadboard. Adhesion at the back sticks really well.

After I wrote my previous review the company reached out to me directly and offered to either refund my money or to send replacements as they had fixed a design flaw. I chose the latter as I needed a new set. Whatever they did, it fixed the previous issue with the bad traces. The new boards have had no issues. The one thing I will note is that the board is EXTREMELY tight. I thought I was bending components because I was putting too much force, but my daughter had the same issue. It was easily remedied by pushing a spare jumper in each one a few times to get the contacts to open. A shade tedious, but the boards great and I don't worry about things falling out! Previous review: I have a breadboard power supply that I use, which has a controlled voltage on one side and on the other side, it's whatever is coming into it. On most of my breadboards this works fine, however, I started getting feedback and it started yelling at me that it was getting voltage coming into it as well. Wouldn't recommend just due to that alone.

At this price it makes sense to do modular prototyping, for instance, connecting and debugging a 20x4 display and 4x4 matrix keypad on one board, 16 bit A/D converter, and amplifier on anothe, and so on, rather than cramping it all onto one breadboard. Only time will tell if they'll endure multiple insertion cycles, but so far they've clamped tightly to IC pins, 24 AWG solid wire, and Dupont cables.

A lifechanger for prototyping circuits! Instead of tying wires together, I was able to use this breadboard to easily test connections between different components. The breadboard carries current well and has great documentation. I was able to set up a circuit in minutes!

*update* Elegoo very graciously sent me a new set of these and I can confirm that the initial ones I received seemed to be duds that snuck by Quality control. The new breadboards have none of the issues I originally reported, the power bus strips work just as well as my very expensive breadboard and the rest of the bread board holes grip components firmly but without the excessive force that was required on the one I originally had trouble with. Elegoo's customer service was exceptional, It is great to see that there are sellers willing to help their customers when they have an issue! I look forward to purchasing more items from them in the future! I have left the old review below incase another customer has issues that are similar. -old review- Good things first, these breadboards arrived quickly and are labeled correctly! They are labeled A-J on columns, and 1-60 on rows from left to right. The bus bars are continuous and do not have a break in the middle. Now onto the less great things, they seem to have quite a variety of quality between the three that arrived. Two work okay, one has all the pins from row 30 on slightly offset from their holes so that it is difficult to insert components into it. All three have issues with their bus bars, none of which properly grip (in fact I don't know if they are holding the components at all, they may just be resting on the bottom of the slot.) and as such cause huge issues if using them as power rails. Another issue I had was that none of these would attach to the other 830 breadboards I have (one of which was from the Elegoo super starter kit) their clip points were offset from any of the other boards I have and only seemed to be able to clip together with eachother.

Not bad quality

Update: The customer service team had contacted me and sent me a replacement that was tested didn't have any quality issues like the units i had gotten before, all the pins are contacted and everything seems pretty nice! Would definitely recommend for the price and service Old Review: At first, when I pulled it out of the package, it seemed okay. The plastic seemed sturdy. However, after closer inspection, it soon became a bit worrying. The ink imprints seemed to be past their prime right out of the factory. The cutouts aren't the most aligned, and there are even some chips on the side. Additionally, the power rail side is a lot more loose than the center board. On the bright side, the plastic itself seems to be of high quality, and there isn't much warping on the plate.

Several reviewers have indicated that these breadboards were either too tight to insert wires or too loose to hold inserted wires. I found them to be reasonably good and had no difficulty in building different circuits on them. Even inserting ICs was reasonably smooth. They also arrived on time and in excellent condition.
