ESP32-WROOM Single-Channel Relay Module (DC 5-60V)

Overview:

The ESP32-WROOM Single-Channel Relay Development Board is a versatile and robust solution for smart home automation and IoT projects. Powered by the high-performance ESP32-WROOM-32E module, it integrates WiFi and Bluetooth BLE connectivity with a 5V relay capable of controlling high-voltage appliances. Its standout feature is the wide-range power supply compatibility, accepting DC 5V to 60V, making it ideal for integration into diverse power environments like automotive (12V/24V) or industrial systems. The board includes an onboard programmable LED and button (IO0), and all I/O ports are exported to headers for easy secondary development using the Arduino IDE or ESP-IDF.
