Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- Modbus
- Modbus is an industrial communication protocol used by many meters, sensors, PLCs, and automation devices. Modbus support matters because it can make the controller easier to integrate with existing industrial equipment.
- Modbus RTU
- Modbus RTU is a version of Modbus commonly used over RS485 serial wiring. It matters if you need to connect the controller to industrial sensors, meters, or drives that use serial Modbus rather than Ethernet.
- 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.
