DIN Rail Mount Screw Terminal Block Adapter Module. With the adapter module you can easily extend Raspberry-Pi projects to industrial control applications. Applications for Raspberry Pi A+ 3A+ B+ 2B 3B 3B+ 4B Zero Zero-W. (Now upgraded to Version 1.2, to add support Pi Zero and Pi Zero W. But, you must soldered a 2x20pins male header in your Raspberry Pi ZERO).
CN3 and CN4 1:1 on board connected. CN3 connect Raspberry Pi board. CN4 Extension connector, you can use a FRC 40-pins wire connect to other devices.
