Hello. I’ve used 8 of your PWM signal generator module frequency meter 1Hz-150kHz adjustable on prototyping and find them exactly what I want. Problem is, I’m not sure of the best way to mount them on a project/prototype box. There are four holes (each corner) — screw size? Bolt? Suggestions?

Thanks,
