Product Description Overview:

LC 5V ESP8266 2-channel WIFI relay module is equipped with to ESP-01 WIFI module and 8-bit high-performance MCU, Only needs simple configurations and then you can control the relay with a cellphone APP under LAN area. 

Characteristics:

  1. On-board N76E003/STM8S003 and ESP-01 WIFI module
  2. There are two modes: 
    1. (1) Mode 1: Cell phones carry on the wifi module directly 
    2. (2) Mode 2: Cell phone and wifi module carry on the same router
  3. Additional function: As a USB relay module when unplugging the ESP-01
  4. Transmission distance: (1) In the open environment, the maximum transmission distance is 100m when the cell phone carries on the wifi module directly ; (2) when the wifi module and cell phone carrying on the same router, the transmission distance depends on the router’s signal intensity;
  5. Use Smartconfig technology of ESP8266 to configure the password for the ESP-01 module with APP
  6. On-board 5V, 10 A / 250 v AC 10 A / 30 v DC relay, absorb 100000 times continuously, Module with diode effusion protection, short response time
  7. On-board model selection and working position indicator LED
  8. On-board preserved UART debug interface and MCU program interface
  9. Size: 59*40mm

Interface and sources:

  • IN+, IN-: 5V power input
  • TX, RX: UART communication
  • SWIM, NRST: MCU program interface
  • S1: Mode selection key, default is mode 1
  • S2: Restore key
  • LED D2 and D4(red): Relay indicator
  • LED D7(red): Mode 1 indicator
  • LED D5(blue): Mode 2 indicator
  • LED 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 is waiting for the APP configure the password for it when D6 fast blinks every 0.5S 
    • (3) It means the whole configuration is done and waiting to establish TCP connection with APP when D6 slow blinks every 2S 
    • (4) It means the TCP connection between ESP-01 and APP is OK when D6 is on all the time.
  • Relay control command(must be in hex format): 
    • Open the first relay: A0 01 01 A2 
    • Close the first Relay: A0 01 00 A1
    •  Open the second relay: A0 02 01 A3 
    • Close the second Relay: A0 02 00 A2
