The FRDM-KL25Z does not come with any socket headers in the expansion connector areas. It requires socket headers to be added to the underside of the board.
The parts needed are as follows (or similar equivalent)
1x 12 position (2 row x 6 pin) 0.100"x0.100" Dual row socket.
2x 16 position (2 row x 8 pin) 0.100"x0.100" Dual row socket.
1x 20 position (2 row x 10pin) 0.100 "x0.100" Dual row socket.
**Note these are quite standard parts, and any equivalent sockets will work. You may also be able to purchase a "breakaway" type that allows you to cut a larger strip down to the sizes you need.
It is good practice to when soldering on the socket headers to only tack the two opposite corners. (The headers go on the bottom remember!) This allows checking that the socket headers are flat to the board, and align well to the underlying headers.
