This is kinda a tangent question - but does anything know why different drivers use different type of connections? I find it very annoying.

For example I was using these but had to find female jumpers for the input. I much would prefer terminal screws for everything. I assume some of it may have to do with voltage concerns? But nontheless its a couple cents more to do the terminal screws and seems like it would always be easier.

I've also had the same annoyance with these and this in the last week.

Some 5v relay have this too - thought I always just go with the ones that have pins for everything.

Like I sorta get going with just male pins if you think your users are all amateurs who may not have or want a tiny screwdriver - but once one of your connections needs the screwdriver you may as well make all of them have it.
