Electronics-Salon 10x Prototype PCB for Arduino UNO R3 Shield Board DIY. by CZH-LABS

Awesome blank prototype boards. Just be a bit more careful with where you place your components because some pins are directly above usb & 12v power ports. Quality is awesome. Highly recommendAnd i don’t get why some people gave 4 star because they didn’t pay enough attention to extra pin connection. Mistakes are expected if you work on something ;) only those who don’t do anything don’t make mistake.I only wish these boards would have extra connection pin like that for 5v.

These boards are good quality and do the job.

These boards are exactly what I was looking for to complete my bike computer project atop my Arduino Uno. The boards appear to be of good quality, and they solder well. Other boards I've tried did not take solder easily. The limited component space is understandable given the Uno's small size. The only issue I encountered at the end was that I noticed the A5 trace extended to one extra via compared to all other signals. This migh be a design oversight, but it is clearly shown in the online photos, so it must be a special feature. Sadly I landed my push button pin on this A5 trace extension. I'll just be aware of this trace on my next project.Update: Removed one star. The push button pin I landed on the A5 trace due to the extended length kept my code from loading properly on my Uno. This extended trace resulted in inadvertently shorting A5 to GND in my case. After pulling my hair out over the erratic behavior of my known-good code, I desoldered the push button and moved it one via position away from A5, and this fixed the problem. One star less for my frustration since I'm a new user of these boards, and the extended A5 trace made it prone to error on my first use.

So far so good. They align well and fit the UNO r3 perfect. What little soldering I've done on them seems to take well. Would buy again.

These boards are about the most perfect prototyping boards for Arduino projects I've found. Almost all prototyping boards have predetermined layouts for things like LEDs, pushbuttons, SMT components, etc. which I just don't care about. All I want is a breadboard with plated-through holes so I can lay out any durn way I want. You can choose to use just pins or extender sockets and everything else is up to you. I also use these on Mega 2650 boards, using jumpers if I need to connect to the additional 2650 pins.

These are surprisingly high quality proto-boards and relatively cheap. They can be used to build your own Arduino shield or just flat out build your own Arduino. The traces have the correct numbering including the Uno R3 I2C pins and screw holes. The traces to the pins are also extremely wide to allow for high currents (not that you want to source a lot of power from the Arduinio pins!).

The price was low for the quality of the product received. Would buy again.

These are a great for DIY shields for the Arduino UNO. The are nicely labeled and of high quality with easy to solder through holes.
