🔧 Enhance Arduino Mega Prototyping: KEYESTUDIO MEGA Prototype Shield V3 Board with Breadboard, Ideal for Circuit Building Projects Review

Not sure what I bought here. No diagrams, no printed documentation, one has to guess what connection can or cannot be made to copper on a circuit board. Their website has a "descriptive" video with an annoying music title, poor English, and what appears to be a verbal schematic that you can build on a breadboard using a photocell and an LED. However, there is no description of the built-in circuitry on the prototype PCB itself. Overall, this is a well-executed product, in some ways better than…

Great quality, love the yellow Keyestudio look and no breadboard attached, that's a bonus - me can also use it for soldering projects or for prototyping, both of which have been done with great success so far. The reason for the 4 stars and not 5 is the oddity that all these GPIOs are connected to a breadboard with all the fancy yellow connectors. The 40-pin Mega IO connector on the back is skipped entirely. To use these pins for development as well, you must either add your own f/m pins or…

Protoshield is a pleasure to work with. Be careful where the elements are soldered as there is a possibility of interference from components on the Arduino Mega.

Usually when making a prototype board like this they used a stacking header so the pins go to the end of the Arduino and allows you to stack. This leaves an extra set of pins open for each connection to be soldered. In this case you will have to use Dupont connectors to access the pins as they both used sets of pins. I'm sure it's fine for a one-off test project, but since I'm making a product for humans, everything needs to be soldered.

I used it to find the location of the contacts and made a special "hat" with which I made the connections needed. It appears to be well built and the breadboard looks good. I found the small size of the breadboard a bit difficult to place, but I got what I needed.

The quality of these boards is amazing, especially at this price point. Goes well with the 2650. The packaging is also convincing. (So good I can't bring myself to throw them out. I keep telling myself they can be used in any project.) Really well made product. Highly recommended.
