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 handy little device that can save your system from smoking. A resettable fuse (also known as a PTC) is a resistor that has very unique properties. For this model, if your circuit tries to draw more than 250mA of current (if you have a bad short for instance) the PTC would 'trip' (by heating up). The increased resistance (trip state) would break the circuit and allow only a small leakage current. The leakage current may still be enough to hurt some electronics but it's much less than...
