ESP32 2-Channel 30A Relay Module Bluetooth WiFi Development Board AC220V Support Secondary Development 1. Utilizes the ESP32 module, supporting remote control. 2. Reserved UART pins for easy development. 3. Available with either a DC 5-24V or AC power supply. 4. Equipped with a 5V-30A relay. The ESP32 Dual AC Powered 30A Relay Module is a relay module built around the ESP32 module. In terms of hardware, it features an AC-to-DC transformer module, uses a 5V/30A dual relay, supports UART programming, and provides corresponding pinouts for convenient programming. In terms of software, you can choose to develop using the ESP-IDF development environment or the for Arduino IDE, making it easy to get started and integrate it into your products.
