Emeter_2CH

This advanced control board is powered by an ESP32-WROOM-32E, specifically designed for precision energy monitoring and industrial automation. It features dual-channel energy meter reading capabilities via a robust RS485 interface with auto-direction mode for seamless data acquisition. The design includes two PNP-switched power outputs for controlled DC supply and two high-quality relays capable of switching AC loads up to 200W. For enhanced safety, the board integrates two isolated digital inputs to protect the MCU from electrical noise when interfacing with external switches. This comprehensive hardware suite, rounded out with an onboard OLED display and I2C expansion ports, offers a reliable solution for smart energy management and distributed control systems.
