These stackable 0.1" (2.54 mm) female headers are just the right height for connecting  Arduino Uno, Arduino Mega 2560, Arduino Leonardo. The set includes two 1×6 female headers, two 1×8 female headers, and one 1×10 female header, so it has everything necessary for both old- and new-style shields. Pololu 1035
