HiLetgoNano I/O Expansion Sensor Shield for Arduino UNO R1 Nano 3.0 Duemilanove 2009

Great boards and you can make this stackable even with the Nano board that sits up a bit high. I used the short pin sockets soldered to the board and then plugged in the long pin sockets for extenders to allow the daughter shield enough height to not interfere with this board. Just be creative and have fun with it.

Worked great for my servo project.

I have two complaints. The board isn't cut well and there's a ragged edge. The pins are all skewed slightly.I haven't tested everything, but I've used about 1/2 the pins and they all work fine. This is a good tool for whatever project you're working on.

This breakout board is so much better than using a bread board - because all of the pins are available in "triplets" with the Gnd and VCC, making it super convenient to connect sensors and outputs with DuPont wires or server cables (watch the polarity and pinouts). Well made, will purchase more.

The media could not be loaded. Does what it is supposed to do.This is for my Otto Robots

Complete with no defects that I could find.It simplified the construction of a robot I built.It provides voltage and ground points for each device plugged into it.

After usage with two of my Arduino Nanos, the RX/TX lines stopped working, and I am unable to program either Nano with the Arduino IDE. Definitely don't buy.

I bought this to build an OTTO (ottobot.org) robot with my son. The board worked flawlessly, and the OTTO went together well.
