R31 Prototype Screw Terminal Block Board Kit Terminal Blocks Module

I ordered two of these. There are no instructions, but you just repeat the picture. The first one went like clockwork and fit perfectly into the Arduino Mega. But the second one... I did not pay attention. You are supposed to insert all of the pieces into the side with the writing. I did the opposite and ruined the board. I have been here before, even with the best solder wick available to remove all of the gear from the wrong side never works out. I ordered another one.

Some reviews said the ink screening is not right, but my board is perfect. The screening labels on the board do not line up with the mega board, they line up with the output screw connections and the inner bead board connection points. The board must be assembled so the connections must be soldered on the board. If you can do this, then you will have problems

This makes hooking up to a Mega or Adafruit Grand Central very easy. Having both the terminal blocks and the regular pin array make testing and other items very easy. Assembly, while tedious, is very simple.

Got very frustrated when I figured out that the markings for the pins have nothing to do with what pin they are next to. If you look closely at the photo, you can see that the numbers run past the pins that go directly into the Mega. You have to count the pin holes to figure out which pin you are actually connecting to. The screw terminals seem to be labelled correctly but if you are using a combination of ribbon cables and screwed down wires, be careful and make sure you are connecting to the correct pin on the Mega board.

Using this with a Mega2560 and no problems. It fits great and easy to install pin headers.

One has to assemble this product. While I am a VERY experienced PCB assembler I did it wrong and had to order additional headers to repair my mistake. So what I recommend is check twice B4 U solder.

I say you can wire an Arduino Mega well or you can wire it fast (but not both) this board helps make that feasible too...

it good for testing out your project

I always like to use prototype boards because I do not like having to solder and unsolder wires/parts directly to my boards. I use these on all my Arduino and ESP32 boards. These do make life easier.

It's ok, but there was 11 screw terminals missing, Fortunately, I didn't need all of them, otherwise I would have to return it.

Very nice item. On mine there were a couple of screw terminals that won't tighten but they aren't on essential Arduino pins. You have to solder the terminals so check the screws first and put any faulty ones on pins you're not going to use. Also, the terminal blocks snap into each other. If you don't snap them together only the first few will fit and then you'll find they won't line up with the holes in the PCB. Good value!

I recieved just some parts of my order

Great prototype board to speed up your project. A little pricey but totally worth it.
