This extra long 8 pins header socket with pis spacing 2.54mm (0.1"), can be cut at pin number 4 to obtain 3 and 4 pins header sockets. These socket pins can be bend 90 degrees to form right angle pin header sockets. These sockets mate nicely with modules that have pins parallel to PCB pins. With the use of these right angle pin sockets modules can be inserted to the breadboard for flat mounting.
