Screw terminal blocks are the clean, maintainable solution for PCB-to-wire connections — no solder, no loose ends, easy to swap out later. These 3.5mm pitch 2-pin blocks are a practical size: wide enough for a range of wire gauges, compact enough not to dominate your board, and designed to snap together to build up any terminal count you need.
Key Features
- Pitch – 3.5mm
- Pins – 2-pin per block
- Snap-Together – Link multiple 2-pin and 3-pin blocks side-by-side for custom lengths
- Screw Adjustment – Standard flathead screwdriver, easy to tighten and release
- PCB Mountable – Fits most perf/proto-board (mount diagonally for 2.54mm grid boards)
- Pack of 5 – 5× 2-pin blocks per order
Note: These are 3.5mm pitch — they do not fit 2.5mm spaced PCB holes and do not fit into solderless breadboards.
Ideal For
- PCB-to-wire connections on custom and proto boards
- Power input terminals, sensor connections, and signal wiring
- Any project where re-wiring or maintenance is anticipated
Jargon buster
Plain-language definitions for the technical terms used above.
- PCB
- A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
