Welcome to contact with us ! _x005F_x000D_ DC7-60/5V Power Supply WIFI Bluetooth 1-Channel 30A Relay Module Development Board ESP32 Secondary Development _x005F_x000D_ _x005F_x000D_ _x005F_x000D_ ESP32 single-channel 30A relay development board is a development board based on Espressif's ESP32-WROOM-32E module. The I/O port is fully led out and supports DC7-60V/5V power supply. _x005F_x000D_ Onboard programmable buttons, LEDs and relays facilitate developers to quickly conduct prototype verification and development, and bring more possibilities for loT control scenarios. _x005F_x000D_ After burning the program, it can be directly controlled by mobile phone remotely. The onboard LEDs and relays have functions such as WiFi network configuration and factory reset. _x005F_x000D_ Onboard 1-channel 5V/30A relay, output switch signal, suitable for controlling loads with working voltage within AC 250V/DC30V. _x005F_x000D_ ESP32 supports the use of development tools such as for ArduinolDE/VSCode/Tonny. _x005F_x000D_ _x005F_x000D_ Instructions for use: _x005F_x000D_ The relay control pin is GPIO16, which is valid at high level. _x005F_x000D_ The programmable LED is GPIO5, which is valid at low level. Users can write their own program control. _x005F_x000D_ The programmable button is GPIO0. It is also the burn button. _x005F_x000D_ Relay output terminal: _x005F_x000D_ NC: Normally closed terminal, short-circuited with COM before the relay is energized, and left floating after energization; _x005F_x000D_ COM: Common terminal; _x005F_x000D_ NO: Normally open terminal, left floating before the relay is energized, and left short-circuited with COM after energization; _x005F_x000D_ Colour:blue _x005F_x000D_ Material:PCB+Components _x005F_x000D_ Due to different batches, there may be differences in product appearance and printed text, which will not affect use _x005F_x000D_ _x005F_x000D_ Package Contents: _x005F_x000D_ 1 * ESP32 1-channel 30A relay module _x005F_x000D_ _x005F_x000D_ Only the above package content, other products are not included. _x005F_x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
