The web server is mobile responsive and can be accessed with any device in your local network. For this, Need to short the GPIO 0 and GPIO 3 (Rx) pin on the relay board. Make sure your UART adapter is 5V, but don’t ever use it on a bare ESP module. While inserting the ESP-01, either bend the GPIO 0 or completely remove it from ESP-01 board. This wifi relay is based on an ai-thinker esp-01s wifi module. It is designed based on ESP-01 / 01S WIFI module and can be used for DIY own intelligent switch. Relay Load Capactiy : 10A 250VAC, 10A 125VAC, 10A 30VDC, 10A 28VDC. Serial port output debug information by our default firmwarem baudrate 115200. This is the extended version of esp relay board. Connect Arduino Pro Mini 8Mhz 3. ESP8266 ESP-01 4 Channel 5V WiFi Relay Module 5V IOT Wireless Smart Home Device WiFi Relay Internet of Things ESP-01 Module Board for Phone APP Remote Control. 3V). Screw terminals help user to connect devices and power the supply. LC Technology WiFi Relay - Dual Relay (note, older versions of this board used a baud rate of 9600, so if 115200 doesn't work, try 9600)~ To configure an LC Technology ESP8266 Relay X2, use the following settings Set module to Generic (in module configuration and click save) Step 2: Build ESP8266 WiFI Relay Node. A few lead out pins, from top (left) to bottom (right): Resevered design for temperature sensor DHT22. According to the work mode of WiFi relay module to choose the corresponding mode of ESP8266 WiFi module. 8 relays are connected to GPIOs. 9. 3V regulator and provides for a 5V input. connect GND on Arduino, ESP8266 and power supply GND. gz xw oy tb uz kz hd pc nt wy
