Features:
Great for temporary things you don't want to solder.
It provided a nice platform for wiring circuits to an Ar-duino 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.
Package Included:
5 x Nano Terminal Adapter Expansion Boards
