IoT Wireless Main Control PCBA

The IoT Wireless Main Control PCBA is a compact, double-sided control board for connected security devices, smart locking systems, and other battery-powered IoT equipment. The board centers on an onboard WBR3 wireless communication module and MCU control architecture. It integrates wireless connectivity, device control, status indication, alarm functions, battery management, and motor-control circuits in a compact, irregular PCB layout. The onboard WBR3 module provides a hardware platform for wireless communication, and the main controller coordinates peripheral devices and operation logic. The visible circuit board markings include WIFI, LOCK, WAR, BAT, and related positions on the left and right. These markings indicate integrated wireless communication, a locking function, a warning indicator, battery status, and directional device control. LED indicator lights and onboard buzzers provide visual and auditory feedback for different operating states. The PCBA uses mixed assembl…
