esp32 releay interface
This design is a compact, integrated power and control module that converts an input supply into a stable 5V rail while providing isolated control of external loads via relays. At its core, a switching regulator ensures efficient power conversion, feeding both logic and control circuits. The system uses optocouplers to electrically isolate input signals from the relay drivers, improving noise immunity and protecting sensitive electronics. Status LEDs provide real-time visual feedback, while diode protection and filtering components enhance reliability and robustness.
Overall, it’s a modular and efficient solution for safely interfacing low-voltage control signals with higher-power devices in industrial or embedded applications.
