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.
- RS485
- RS485 is a robust wired serial communication standard often used in factories, farms, and buildings where cables may be long or electrically noisy. It matters because it lets this controller connect to industrial sensors, meters, and control equipment over longer distances than typical hobby serial wiring.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
