•Designed for Nano V3.0: The item is a terminal expansion adapter, working very well for prototyping for Nano projects
•No soldering required. Size is about 2.21" x 1.65" x 0.50" (L* W* H)
•It lables for 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).
•Package Included: 6x for Nano Terminal Adapter Expansion Boards
•You can use this adapter to easily hook up for Nano to an outside world via hook up wires
