ESP32 Single-Channel Relay

The ESP32 Single-Channel IoT Relay Module is a compact and powerful solution for smart automation and Internet of Things projects. Built around the high-performance ESP32-32E chip, this all-in-one board combines wireless connectivity (Wi-Fi and Bluetooth) with a high-current switching relay, eliminating the need to buy separate ESP32 and relay modules.

With this module, you can easily control electrical devices remotely using just a few lines of code or ready-made mobile apps. It’s perfect for building smart home systems, greenhouse controllers, workshop automation, and educational IoT projects. Whether you’re a beginner or a professional developer, this board gives you flexibility, reliability, and fast development in one compact package.
