Odseven 2-pin 3.5mm Pitch PCB Mount Screw Terminal Block for Raspberry Pi
These terminal blocks are designed to 'snap' together. You can attach as many 3-pin or 2-pin ones along as you'd like to make arbitrary length of terminal block. These particular 3.5mm terminal blocks are our favorite: big enough for a range of wire gauges, easy to adjust with a screwdriver, and not too chunky. The only down-side is that they do not fit into 2.5mm spaced holes - but they do fit in most perf/proto-board if you rotate them diagonally . They don't fit nicely into solderless breadboards. Nothing makes a project harder to maintain than a lot of loose wiring. That's why we like to use terminal blocks whenever making PCB-to-Wire connections. It is installed on the PCB board. Used widely in the electronics, communication equipments, instruments, calculator, automatic control system, domestic appliance and warning devices, etc.
Thanks for your attention,hoping you will have a nice shopping!
