Treedix Screw Terminal Block Breakout Board Moduleor Compatible with Arduino MEGA-2560

I feel like this product has been unfairly down rated because people didn’t bother to read the description or just generally have no idea what they’re talking about. Yes, you have to solder it together, that should be obvious if you looked at the pics or read the description. The “special tool” needed to insert/remove the wire is just a small screwdriver. These are not “screw terminals”, they are better. Screws can loosen leading to loose wires, spring actuators are much more reliable, especially if the unit will be exposed to any vibration. The quality is good and if you’re at all competent with a soldering iron this should take maybe 30 min to assemble.

Description is wrong. This is not a screw terminal block. And also, who would use a screw terminal shield that you have to solder together yourself? The whole point of a screw terminal shield shield is to AVOID soldering connections. This product has a deceptive title and makes no sense.

Great product and great seller communication. If you're good at soldering (like I am) then get this one and save yourself the money you'd spend on a pre-assembled one. It's got a good quality PCB and components, comes with a jumper kit, and you get to decide if you want pass-through or standard header pins (both are inlcluded) - all in a reusable box. The stickers were missing with my kit, but the seller was very quick to make it right; it took 2 weeks to get here from Asia, but that is expected. I'm probably going to order another one soon.

I bought by mistake not realizing it had to be assembled. Bought the assembled version for a few dollars more.

As others have mentioned, this does not have screw terminals, it has a push-to-open type of connecter that works well enough if you use the tool they send with it, but I would have preferred to have screws. The screw type terminals would require less pressure pushing against the board stack. If the stack is not mounted (ie: lose on the bench) it becomes a three-hand proposition to make connections. I did not realize at first that it comes with both stackable headers and regular headers. The stackable headers are the very common ones that have rectangular pins, not square pins. The square pins (which the other headers have) are more reliable, IMHO, so those are the ones I soldered to the board. You won't be stacking any other boards on top of this anyway, the only advantage of the stackable headers are that you can insert wires into them, but then why buy this board if you are going to do that? The ICSP header is included, but is only pass-thru and has no screw terminals associated with them that I can find. So, there is really no point in soldering this header in place if another shield will not be stacked on top of this one.

Great product, worked very well. Needed this to keep my wiring attached in an arduino that was mounted upside-down. Worked perfectly.

Solid, seats squarely and firmly, holds wires well.

First off this does not come with screw terminals. You need to use the flat blade provided screw driver to push rather hard down on the orange tab and place your wire in. I found that I needed a length of at least 8mm (5/16”) for it to hold the wire once you release the pressure on the tab. I was able to use 16g wire and I am not sure if larger would fit. Otherwise satisfied except I would prefer to have screw terminals over the spring terminals as the description stated. Yes, I am keeping the product since I already soldered the terminals on the board. Removed a star for improper description.
