ElectroCookie Prototype Board Breadboard Style PCB Solder Board for DIY Electronic Projects, Compatible for Arduino Projects, Gold-Plated (6 Color Pack + 7 Screw Terminal Block Connectors)

These are well made and a very useful design. Plated through holes. Pads take solder well. No oxidation present. Neatly packaged. Nice variety of colors. Perfect size for transferring most breadboard protos to a circuit board easily. Nicely labeled pin locator text on the board, but beware … locator alpha characters front vs back are inverted so hole A1 on one side is hole J1 on the other. Ground and power traces on both sides of the board is very convenient & useful. The mounting hole options are excellent.Would emphatically recommend.I’ll buy these again.The screw down terminals are a nice and curious little addition, but the solder pins do not fit the +|- power rail spacing of the holes at the edge of the board. They will fit into holes elsewhere on the board though, just plan ahead, and they’re useful in other ways or for other projects.

These have a nice feel, look really good with the many colors and seem to be a good quality. Soldering on these is easy.My only issue is this item came with 7 Screw Terminal Block Connectors. The obvious choice with those is to use them to power the boards +/ - rails. These terminal blocks are too big to fit the power rails (They take up 3 holes) on a breadboard and the +/- through holes at both ends in the middle of the board. 2.54mm terminal blocks would have been better instead of the 5mm they sent. 2.54mm would only have a 2 hole footprint, work anywhere on the board including the power rails.

I used this board to create an IOT solution that monitors my hydronics (solar hot water) system, heats my greenhouse and controls the fan in my root cellar.I got pretty creative by cutting into the rails and creating a 5V rail, a 3.3V rail and a consecutive series of holes (on which I placed connectors) for DS18B20 sensors.I have an ESP32 development board and a breadboard power supply on it. I also have connectors for (6) DS18B20 sensors, (2) DHT22 sensors and (3) relays.This board looks really good, the writing is easy to read and it's thick enough to be sturdy.Now, I'm working on an enclosure design that I will 3D print and everything will be tucked neatly away.Highly recommended.

What else can I say? These are fantastic boards. I've used 8-9 on different projects, a couple stuffed full of different components, and found they are rather robust. No flex in the board at all, I mean you can if you tweak it hard enough, but that takes some serious effort. I like the power rails that trace the outer edge of the board which makes for short runs to components that need some juice. Will for sure order more of these as the need arises.

It was a pleasure using this to migrate my breadboard prototype to a permanent implementation. Loved the simple way to bridge power and ground on both sides with an easy solder. Watch out for the lettering on the bottom. It’s reversed from the top. eg. column A on the top is J on the bottom. I’m new to circuits, but someone please tell me how that’s a good design.

These are the best quality solder prototyping boards I've found after using dozens from several brands. They solder well, and are mostly compatible with similar boards from Adafruit (my 2nd choice). The power rail jumper option is a very handy feature. The solder mask colors are nice if the board will be visible. I just placed another 2nd order for these.

These boards are EXCELENT because they have a POWER and GROUND buss running down both sides. Especially useful when that's what you need.

These boards are very well made. They are sturdy and easy to solder. The print is clear and easy to read. I will be purchasing more in the future.
