I love these! Actually ordered 10 of them! These are awesome for moving a prototype circuit from a breadboard to a more permanent solution. They also make it very easy to power your project too with the barrel connector on the board (almost any 7.5 to 12V center positive adapter will work). Construction and materials are great.

Comes with sets of header pins, but you don't need to solder, you can just seat the nano male to the terminal's female block and you're ready to roll. Used it to control a strip of LED lighting, was more than capable, and required no troubleshooting, just worked as expected.

I love these boards, makes interfacing so much easier and quicker, no soldering and can use male jumper wires.

This terminal block works great for interfacing the Nano to other devices or computers. Much better than a prototype board.

Very handy boards. I used these to make some light controllers for Christmas lights. They are great for prototyping or making professional looking one off projects

Quick and easy way to pinout and power a nano. Great for when you need the convenience of a full size arduino with spinouts etc. but need it in a smaller package

I’ve only used one of them so far, but it is exactly what I was looking for.

Muy práctico para instalar arduinos nano.

Came as expected. Looking forward to trying them.
