Here we have some right-angle headers with 40x3 pins. They are break away and will take a bit of effort to break this beast where you need it to break. That being said, if you need a big header like this, it's easy enough to break it where you need. The pins are spaced at 0.1" and there are 3 rows of 40 pins. These work well in the UAV boards listed below.

This is a glass ferrule type fuse. It fits great with our 5mm fuse clips. The fuse is rated for 250VAC, up to 500mA. Fuses are pretty simple, if more than 500mA pass through the fuse, the small filament inside the fuse heats up and breaks (like a light bulb burning out). The circuit is then broken and hopefully your circuit is saved from molten destruction. For smaller loads, you may want to checkout a PTC (aka resettable fuse) listed below. These handle less current (500mA) but can be set and...
