IDC40 2x20 Pins Male Header Breakout Board Terminal Block Connector with Simple DIN Rail Mounting feet

I use it for prototyping AI computer vision. I added pins into each to make my female-to-female wires easy to move around. I also color coded some labels. I checked all the 40-pin numbering from the open end of my 2x20 pin flat cable to the screw connectors and I found no error.

This filled my requirement to combine a great many free wires with a ribbon cable.And this contributes to a very neat installation for hard wire remote control.

This is a great product. I been using the pi gpio extender 'hats' they work but dupont connectors are not very heavy duty.The screw terminals on this are great. They don't come lose or get bent when adding new connections. I don't have to touch the pi to add new connections which is great. Also can use larger gauge wire than dupot connectors allow. (saves time!) Geat product!

solved my problem.

Works, but is huge. Didn’t need to be so tall in my opinion.

Very Nice quality and build.

the pin numbers on the relay are wrong. i finally figure it out that they were labeled wrong. i wasted a lot of time trying to figure out what was wrong with my ECU connection.

the ribbon cable clips keep ribbon cable from getting unplugged.
