Ultra-Small GPIO Terminal Block Breakout Board Module for Arduino Mega-2560

Since parts are small, a little difficult to screw in the supports but, very stable once installed. The terminals worked perfectly and the pins fit snugly without tightening too much. Well labeled. I recommend securing wires before connecting to the Mega board if you’re just transferring. I Highly Recommend.

Installs nicely. Wires connect at edges so important LEDs on board are not blocked. A good jewelers screwdriver is easier to use than the provided screwdriver. The nylon standoffs are fairly delicate so a light touch is needed. Extra standoffs are provided in case of problems.

Good product, fits up well with the mega but the nuts are nearly impossible to fasten on. It would be cool if there was a tool to help with fastening them to the bolts.

Well made, good form factor, a real timesaver. Easily install, relocate wiring as required. A bit pricey, but anymore what isn't.

Usable but sloppy workmanship. I bought two sets. Some minor bowing evident in one set and more serious bowing of one of the longer pc/terminal strip boards in the other. Connections appear to be okay but it is not ideal especially at the high price they are charging for the kit. Nylon standoffs are terrible! It is best to assemble the longer standoffs loosely to the strips before pushing the strips into the headers on the controller card because threading the tiny nylon nuts onto the standoff is nothing short of a nightmare. Fortunately, they include some extra standoff pieces which you may need if you are not really careful with this nylon trash. Assembly documentation not strictly required but at the price they are charging a simple picture of the finished assembly would be nice.

Works as advertised

If you have a project where your Mega is wired up in use on a somewhat permanent basis these connectors fit the bill. Nicely made, fit well, hardware is OK. Not a Phoenix, but not the Phoenix price.

I like the idea but it would be nice to have some screws to attach the Arduino to something.Sometimes it would be nice to be able to add shields. This arrangement does not allow that.
