IoT Main Control Board PCBA

This IoT main control board PCBA for connected commercial equipment supports sensor monitoring, load control, logic processing, and cellular communication on a single, centralized electronic platform. The board carries several functional sections: sensor input circuits, control and signal-processing circuitry, load-control components, power-related circuits, and a dedicated 4G communication section. Connections for water level, water shortage, water inlet, and other external signals allow the main control system to collect and process operating conditions. Production mainly adopts SMT assembly, supplemented by the DIP assembly process. 4G communication module and a SIM card slot provide cellular connectivity for IoT applications. Depending on the final system configuration, the control system can transmit equipment data through a mobile network. Multiple wire-to-board connectors and pin headers provide connections for sensors, peripheral devices, and other functional modules, and the…
