Description:The 5V dual WiFi relay module uses ESP-01 as the WiFi module and is compatible with 8 bit MCU chips. Only a simple configuration process can realize the wireless control of the 2-way relay by using the mobile phone APP in the LAN.
Features:Onboard ESP-01 WiFi modules and high-performance microprocessor STM8S103.The use of Smartcongig technology in the mobile phone on the APP ESP-01 WiFi module to complete the account and password configuration, configured username, and password memory function.Board mode selection and real-time working status indicator.Reserved UART debug interface and STM8 SWIM program download interface.Control Voltage: 5VOutput Voltage: 250Vac , 30VDCOutput Current: 10AInterface: UARTSize: 59mm x 40mmOperating modes of work:Mode 1: mobile phone is directly mounted on the WiFi module.Mode 2: mobile phones and WiFi modules are equipped on routers simultaneouslyAdditional function: it can also be used as a USB relay when ESP-01 is pulled out.Interface and sources:IN+, IN-: 5V power inputTX, RX: UART communicationSWIM, NRST: MCU program interfaceS1: Mode selection key, default is mode 1S2: Restore keyLED D2 and D4(red): Relay indicatorLED D7(red): Mode 1 indicatorLED D5(blue): Mode 2 indicatorLED D6(green): Working state indicator, the description of D6 as below:(1)It means internal self-configuration or lost connection with the router when D6 off(2)It means the ESP-01 are waiting for the APP configuration the password for it when D6 fast blink every 0.5S(3)It means the whole configuration is done and waiting for establishing TCP connection with APP when D6 slow blink every 2S(4) It means the TCP connection between ESP-01 and APP is OK when D6 on all the time.Relay control command(must be hex format):Open the first relay: A0 01 01 A2Close the first Relay: A0 01 00 A1Open the second relay: A0 02 01 A3Close the second Relay: A0 02 00 A2
Package Include:1 x ESP8266 Dual WiFi Relay Module
