This Tiny Stripboard Shield project can be used for making a number of different Arduino shields. The stripboard shield uses standard height pin headers, so no specialised headers need to be ordered to build this project.
Because one of the Arduino Uno headers is offset and won’t line up with the stripboard holes, only three of the Arduino headers are connected. There are still enough pins from the Arduino to be able to build some small projects (hence the name Tiny Stripboard Shield).
The reason that one of the Arduino headers is offset is so that it is impossible to connect a shield the wrong way around.
