Jargon buster
Plain-language definitions for the technical terms used above.
- 3.3V regulator
- A 3.3V regulator is a power circuit that provides a steady 3.3 volts for parts that need that supply voltage. On a breakout board, it can let the sensor run safely even when the connected microcontroller or power source uses a higher voltage.
- 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.
- transient response
- Transient response describes how quickly a power supply recovers when the load suddenly changes, such as when a circuit switches on a motor or radio. A faster response helps keep the output voltage stable during sudden current changes.
