ESP32 single-channel AC power supply 30A relay module is a relay module equipped with ESP32 module. In terms of hardware, it is equipped with an AC to DC transformer module, uses a 5V/30A single-channel relay, supports UART burning development, and reserves the corresponding pin interface, which is more convenient for burning. In terms of software, you can choose the ESP-IDF development environment or develop on for the IDE, get started easily and quickly, and apply it to the customer's products. Use ESP32 module to support remote control. Reserve UART pins for secondary development. Supports AC220V input and output. Equipped with 5V/30A single-channel relay.
