Components & Parts / Terminal Blocks

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. 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...

Spring terminal blocks will simplify your wiring and make your project more rugged. Instead of soldering wires to your perf board, solder in these 0.1" pitch terminal blocks. There's a little spring contact so you can pull back on the plastic bit and slip in your 20 to 26 AWG solid or stranded-core wires. Each terminal block is electrically isolated from those next...
