The header pins on the Core are spaced at an interval of 0.1", which is the standard pitch size for proto-boards and breadboards. The physical layout of the Core was inspired from the [http://arduino.cc/en/Main/ArduinoBoardProMini carte Arduino Pro Mini ]. | The header pins on the Core are spaced at an interval of 0.1", which is the standard pitch size for proto-boards and breadboards.
