I've been using these for a few months now for Arduino project prototyping, and I think they are awesome! I found some how-tos for using 30 awg coil wire for prototyping, and what I do now is lay out female headers on this board for my components (typically an arduino nano, components for using LIPO batteries, and a soft-latch switch that's really useful for letting the Arduino turn itself off), solder the headers onto the protoboard, then on the reverse side, use the coil wire to solder the circuit underneath. I use the pads on each end of the board for connecting external wires/connectors. I'm not at the point where I'm ready to have one of the Chinese mfg sites make PCBs for me, nor do I have the knowledge yet to create the right drawings to support that. This method is quick, easy, and I end up with a high quality prototype that is solid and easy to work with, and easy for me to scavenge parts when I'm done while still saving the circuit if I want to revisit that project.

The boards are high quality - every hole is through plated and there is solder mask unlike many other prototyping PCBs. The pads on the ends are also a nice touch, as they make it easy to mount header pins on the edges. Finally, the price is a steal. I'd end up with only two boards if I paid the same amount at an electronics store.

Not much to say about this product it's a pretty simple product. The breadboards they are very high quality. The copper contact points are very strong and do not seem to rip off like some bread board contacts do. The shipping time was okay in the seller seem to be very responsive. In the future when I'm in need of more bread boards 4 small electrical projects I will definitely be coming back and purchasing more. They were shipped in a padded envelope and the product was not damaged during shipping. Like I said there's not much to this product but if you're in need of smaller bread boards for electronic projects this is a good place to go.

The boards that I received did NOT have the screen printed columns and rows. They have the letters across the top on one side (A through T) etched/melted into the board - you can barely see them. On the other side of the board, the letters are across the top and bottom - but in the opposite order from the other side, so they do not match up. Putting a wire in A on one side looks like T on the other side. The numbers (01 though 14) are on both edges on both sides, in a consistent order, but again, not printed on the board, but etched/melted into the board and impossible to read without a magnifying glass and great light. CAT5 wire fits into the holes with ease. I have not soldered one up yet, waiting for more components to build some MySensors.org projects.

These PCB's are through hole plated. Very nice boards for the money. I believe these are the same boards that many of the big electronics distributors sell for upwards of $2.50 EACH!My only gripe would be that the 4 screw holes at the corners are a bit small. A standard 2-56 screw just BARELY fits through the hole. If you need bigger screw holes you should expect to have to sacrifice some of the pads on the board because the existing screw holes are too close to the edge to be drilled out to a larger size.Other than that, you really can't beat them at a little over 50 cents apiece shipped to your door.

The leads tend to come off when soldering. Be careful with your temps when working with these. Decent board otherwise.

I have had more than enough frustrations with prototype boards tossing their copper as soon as a soldering iron gets close to them. Trying to diagnose a non-working circuit and discovering that the traces lifted off the board is annoying as hell, and I am happy to have found a source for prototyping boards that do not exhibit that problem. These are solid, substantially built, with pads that do not lift, strong enough to survive multiple component replacements. I will definitely be ordering more of these.

Perfect size for DIY guitar effects pedals (big enough for the more complicated RunoffGroove and DIYstompboxes projects or building a simple distortion circuit and a Lil' Smokey onto one board) and other small electronics projects; I expect I'll be able to put a Smokey and a Tweed-y preamp on one of them for a grab-and-go busking amp. Plated-through holes are a bonus and hard to find at these prices from the typical electronics suppliers.For those used to single-sided protoboards, be aware that plated-through holes are a bit more thirsty for solder because of the larger surface area. This also makes them a bit harder to desolder, but the upshot is the pads aren't going to lift on you.

Very good product and fast shipping

Very handy little protoboards.

thank you
