Description
This 4-channel relay switch module is engineered for reliable control in smart home and light industrial environments. It combines a 2.4GHz Wi-Fi transceiver for integration with standard IoT platforms and mobile apps with a secondary 433MHz RF receiver for backup local control via handheld remotes. The module’s four relays are rated for high-voltage AC/DC loads, providing robust isolation and fast switching times.
Designed for continuous operation, the board features a wide input voltage tolerance and low quiescent current, making it suitable for battery-backed or solar-powered installations. The integrated microcontroller manages network connectivity, timing logic, and relay driving, offering a turnkey solution for automating HVAC, lighting, pumps, and other electrical devices without requiring deep embedded programming.
