2X DC7-28/5V Power Supply WIFI 2-Channel 30A Relay Module Development Board ESP32 Secondary Development Kuvaus

ESP32 dual-channel 30A relay development board is a development board based 's ESP32-WROOM-32E module. The I/O port is fully led out and supports DC7-28V/5V power supply.
Onboard programmable buttons, LEDs and relays facilitate developers to quickly conduct prototype verification and development, and bring more possibilities for loT control scenarios.
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.
Onboard 2-way 5V/30A relays, output signals, suitable for controlling loads with working voltage within AC 250V/DC30V.
ESP32 supports the use of development tools such as for ArduinolDE/VSCode/Tonny.

Instructions for use:
The relay control pins are GPIO12 and GPIO13, and high level is valid.
The programmable LED is GPIO5, and low level is valid. Users can write their own program control.
The programmable button is GPIO0. It is also the burning button.
Relay output terminal:
NC: Normally closed terminal, short-circuited with COM before the relay is energized, and left floating after energization;
COM: Common terminal;
NO: Normally open terminal, left floating before the relay is energized, and left short-circuited with COM after energization;
Colour:
Material:PCB+Components
Due to different batches, there may be differences in product appearance and printed text, which will not affect use
