KEYESTUDIO 10PCS Proto Shield for Arduino Mega, Double Sided PCB Prototype Shield Solderable for Arduino Mega R3 2560

I needed to get some boards to make custom sensor shields for several arduinos, so to save time I picked out and bought four different kind. This set turned out to be the winner. It's got more perfboard space than all the others and the quality is great. It's got a spot for the SPI header if you want to use it, and the perfboard grid aligns with it so you don't waste space or have to avoid it if you're not using it. Silk screen markings are also very helpful. Good value for the money too. But you have to buy your own stackable headers. I recommend listing B0B3XBYL3J for the side headers and listing B084Q4W1PW for the end block if you need it. (you will have to trim two columns off the end)

These are high quality double sided boards. I have beat them up and have not had a failure of a pad. I used one with an ESP32-S3 and basically made a stack-able ESP Arduino. The pin numbers don't mach up so pay attention.

This is a lot better when connecting peripherals to the Mega 2560. Perhaps a couple switching Transistors or an IC for additional functionality. The connector on the Mega can and will wear over time. Or simply make a flimsy connection. This solution is a good choice to get a solid connection. I use them shields primarily to solder connection header to it. This way I reduced the plugging in and out to a minimum without wearing the header on the Mega. The only thing that I found annoying, was on the double row header of the Mega, the RTN (GND) and the 5V is not routed to any pin on the shield. Ergo, they can not be used or connected to a header. There is no room to route a wire to a solder pad. Well, yes one can, but it will look ugly. Only direct soldering to the pins. But the Mega provides other GND and 5V connections, elsewhere.

I'm really pretty stingy with 5-star ratings; a product has to really go above and beyond to get one. This is one such product. This manufacturer went out of their way to make these proto boards really nice and sell them at a very friendly price. I've bought a lot of proto boards, and I tend to try to keep these back for "best", using up all my poorer ones for junk projects.

I've used these boards for several projects. Good quality and price.

Build quality is good but just isolated individual pads , not interconnected stirips of pads like you would expect for a proto project. Dissapointing.

Exactly as advertised, would use this vendor again

Great quality, heavy duty board. Solders beautifully. It serves its purpose, unless you want to stack something on top of this board. There is not enough rows to add female headers for stacking.

Günstig im Preis und top Qualität !

期待通りでした。

Arrived quickly. The product and packaging looks good. Dimensions are accurate, although the signal names are slightly shifted away from where the pins are located. It would have been nice if the header connectors were included in the package or if a "HEADERS NOT INCLUDED" notice was written in the description. It would not be fair to give a bad rating solely because I did not take the time to read the description carefully enough to notice that they were not mentioned. Therefore, the best thing I can do is write it in capital letters in this review hoping it will help someone else :)

店に売ってなかったのでここにたどり着き購入しました とてもよく出来た作りでまた必要になったらここで購入しょうと思います
