Jargon buster

Plain-language definitions for the technical terms used above.

DC: DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
I2C: I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
LiDAR: A sensing method that uses laser light to measure distance and build a 3D picture of the surroundings. It matters for robotics and autonomous systems because LiDAR data can help with mapping, navigation and obstacle detection.
lux: Lux is the standard unit for measuring how much light falls on a surface, similar to how a light meter reports brightness. A sensor that outputs lux gives readings that are easier to compare between rooms, outdoor conditions, and different projects.
microcontroller: A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
UART: UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
UAV: UAV stands for Unmanned Aerial Vehicle, an aircraft that flies without an onboard pilot, such as a drone or autonomous aircraft. Because airborne platforms have limited payload, factors like weight, power draw and any positioning features such as GNSS or RTK are often important considerations.
