Product Review

This is a small and simple Arduino nano expansion board.
It will lead out all the Nano pins, it is convenient for us to wiring and experiment.

Features:
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.

Size: about 2.21" x 1.65" x 0.50" (L* W* H)

Package Included:
5 x Nano Terminal Adapter Expansion Boards
