Use smaller connectors

So, do you have any suggestions on where we might obtain these little scamps at a price that doesn't make my lower lip quiver and my eyes water?

The sizing of the connectors is normally such that you can make any size connector by combining 2 and 3 way to get the number of poles that you need (just make sure before you buy.) Priced as singles this will work out as more expensive, but if you make all your connectors out of 2/3 way units, you will go over the 10 or even 25 piece price break. Not a great saving, but a saving nonetheless.

I hate those terminal blocks

I recently did a project development where I foolishly specified those terminal blocks.  90% of our time was taken connecting the IO devices and debugging the wires not having made good connections

The first revison to the board was to get rid of that damned termina blocks and replace them with square pins.  Crimping pins on wires and pushing them into housings saved so much time.

 

Plus, as a bonus: you won't be using ALL those terminals at once (or if you are, god help you).  So why pay for the expensive terminal block instead of cheap pins for the default case?

Of all the exhibits in the Pre-Apocalypse Era Museum, Breek was always in awe of the unearthed details and true-to-scale reproduction of a technological creation space that the long gone humans had once inhabited.
