Jargon buster
Plain-language definitions for the technical terms used above.
- Axial
- Axial components have one lead coming out of each end, so they lie flat or span holes on a circuit board or breadboard. This matters when checking whether the resistor will physically fit your prototyping or through-board assembly method.
- Forward voltage drop
- Forward voltage drop is the small amount of voltage lost across a diode or diode-like circuit when current flows through it. A lower drop is important because it wastes less power and helps keep the rest of the project supplied with enough voltage.
- reverse polarity protection
- A circuit feature that helps protect the board if power is connected the wrong way around. It matters because it can reduce the chance of damaging the breakout during wiring mistakes, especially in classroom or prototyping use.
