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.
- AGV
- An AGV, or automated guided vehicle, is a mobile robot used to move materials without a human driver. This matters because controllers used in AGVs need reliable communication and industrial I/O for motors, sensors, and safety systems.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- 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.
- I2C address
- An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
- 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.
- 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.
