HiLetgo3pcs Nano V3.0 3.0 Controller Terminal Adapter Expansion Board Nano IO Shield Simple Extension Plate for Arduino Mano AVR ATMEGA328P

These look and seem to work great. I found no problems using these.

I've been using the HiLetgo 3pcs Nano V3.0 Terminal Adapter Expansion Board with my Arduino Nano setup, and it’s been a huge help for easier wiring and prototyping. The screw terminal connections make it much simpler to attach wires securely without needing a breadboard, which is great for more permanent setups.One of the best things about this board is that it breaks out all the Nano’s pins in a clear and organized way, making debugging and adding components much easier. The build quality is solid, and everything fits snugly without any loose connections.

I have tried other nano shields that are not as convenient and less reliable than this one. Great product.

Paired with a Arduino nano, this helps to connect to other modules. Good for prototyping.

Does what it’s supposed to. Screw terminals keep wires tight.

This is a very good value and quality. I am not very good at soldering and something like this was perfect to make my work easier. Sure it makes the Nano triple the size but it is soldered well and makes connecting wires much easier. My only warning is the holes for the cable is very small. You can barely squeeze in two 22 gauge cables per hole. It was a very tight fit. You will have to put some solder on the tip of the cables and squeeze them with a plier to fit more than one cable. It is still snug. But i will still recommend this to anybody who is a novice at wiring and don't mind the added size.

Used them for expansion off Mega 2560. Worked fine for that.

Very good product hi quality
