Great for temporary things you don’t want to solder.
It provided a nice platform for wiring circuits to an Arduino Nano. It can be used in conjunction with or in place of a breadboard.
It lets you make a temporary circuit without the reliability issues you get with prototyping boards, but maybe need a bit more effort.
You need to use your Nano to hold the black pin headers straight and flat during soldering.
5 x Nano Terminal Adapter Expansion BoardThe item is a terminal adapter, working very well for prototyping Arduino Nano projects
It can connect a large number of digital lines to an Arduino while maintaining the footprint of the original Nano
You can use this adapter to easily hook up Arduino Nano to an outside world via hook up wires
Attention: maybe need some assembly
It lables for Arduino Nano version 3.0, however you can still use this adapter for the older version (just have to remember that A0-A7 are in the reverse order)
