ESP32-C3_IoT

This IoT control board is powered by an ESP32-C3 SuperMini, featuring a compact and robust design for industrial and automation applications. It integrates two isolated digital inputs through optocouplers and two high-quality relays to safely interface with high-voltage equipment while maintaining electrical noise immunity. For communication and expansion, the board includes an onboard RS485 interface for long-distance wired networking and dedicated I2C ports for various sensors. The power management system utilizes a high-efficiency buck converter to ensure stable operation across a wide input voltage range. This versatile hardware configuration makes it an ideal solution for smart home projects, remote monitoring, and distributed industrial control systems.
