This product is a terminal expansion adapter designed for Arduino Nano V3.0. It breaks out all I/O pins of the Nano to labeled screw terminals, enabling direct connection with standard hook-up wires. No soldering is required—the board comes fully assembled and ready for use.
It is compatible with older revisions of the Nano; however, users should note that analog pins A0 through A7 are in reversed order on earlier versions. The adapter can be used either in conjunction with a breadboard or as a standalone replacement for temporary or semi-permanent circuit setups.
The physical dimensions are approximately 2.21 inches in length, 1.65 inches in width, and 0.50 inches in height (2.21 × 1.65 × 0.50 in). It is intended for use with ATMEGA328P-based Arduino Nano modules.
