Jargon buster
Plain-language definitions for the technical terms used above.
- 5G
- A mobile network standard used for high-speed wireless data links. If a project uses a 5G gateway, its power system must be able to supply enough current reliably for outdoor or remote operation.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
