micro: Circular RGB LED Expansion Board

Jargon buster

Plain-language definitions for the technical terms used above.

Boson

Boson is a modular electronics system that uses plug-in cables and modules to connect sensors, buttons, displays, and controllers without much wiring. If a cable is marked for Boson, it is intended to fit that connector style and pin arrangement.

Gravity

Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.

RGB

Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.

spectrometer

A spectrometer measures light across different wavelength bands instead of giving only one brightness value. This matters when you need to compare colours, identify light sources, or measure reflected light more precisely than with a basic colour sensor.
