The components include USB Type C connectors, THT LED lights, RJ45 connectors, current sensors, Arduino boards, capacitors, diodes, op-amps, relays, resistors, screw terminals, SIM modules, and many more.
The components are described by their name and a brief description of their function. The library contains 80 components including connectors, headers, LEDs, sensors, ICs, and other electronic components. This is a list of components in an Altium library. An Altium library that I've been making over the years.
