We love little tool hacks like this. If you are too lazy to snap 8 pins off a 40 pin strip, maybe you’d like some help. If you’d rather go with a custom PC board, you might start here.

The headers feature custom pin sizes in mating lengths of from 0.105" to 0.685" and tail lengths of 0.120" to 0.140". The rugged header wafer can be easily broken to fit as needed.
