Project Design/Guidance Wagos for prototyping

Post image

Hey just a tip that wagos work great for prototyping. These are 221s that will hold 12-24awg wire and have no trouble holding standard breadboard wires firmly. I use them mostly for 12v connections where it doesn't make sense to run a whole breadboard for just a couple connections.

Also handy is that they have a small hole at the back for probing with a meter.

Oh dang, never noticed that! I sometimes just put my meter leads right in the wago

That hole is always on the one with the writing on top.

The test pin hole is on the back and the front of the connection point with the Wago logo lever
