1.IN+, IN-: 5V power input
2.5V, TX, RX, GND, IO0: program download interface
3. Button S1: short press to switch mode, long press for 2S to clear password
4. Button S2: reset button
5.LED D4 (red light): relay working indicator light, lights up when turned on
6.LED D2 (red light): power indicator light
7.LED D1 (green light): mode indicator light, described as follows:
(1) When turned off, it is mode 1
(2) When 1S flashes once, it means waiting for the mobile APP to configure the WIFI account and password for the ESP8266 module.
(3) When it is always on, it means the TCP connection has been successfully established with the mobile phone.
8. Relay output terminal
COM1: public terminal
NC1: Normally closed terminal, short-circuited with COM1 before the relay is closed, and left floating after closing.
NO1: Normally open, the relay is left floating before closing, and short-circuited with COM1 after closing.

Use description
1.Tool software
(1) EspTouch_Demo software is used to configure the WIFI account and password for the ESP8266 module when using working mode 2 for the first time.
(2)EasyTCP_20 software, used to send relay control instructions
2.Preparation
(1) 5V/1A power adapter, connect the positive and negative poles of the power supply to the IN+ and IN- of the module respectively.
(2) Install the APP "EspTouch_Demo" on the Android mobile phone, which is used to configure the WIFI account and password for the ESP8266 module when using working mode 2 for the first time.
(3) Install the APP "EspTCP_20" on the Android mobile phone, a TCP transmission tool, used to send relay control instructions, click "SWITCH"
Then long press the gray square in the interface to enter the name and content of the relay control command (the command format is HEX format)
3.Use description
(1) Working mode 1 (the mobile phone is equipped with the ESP8266 module)
①Power on the module
②The mobile phone is connected to the AP hotspot signal sent by the ESP8266 module
③Open the "EasyTCP_20" APP, click "CONNECT", enter the IP address: 192.168.4.1 and port number 8080, and then click "Connect"
After the connection is successful,Click the gray square to send instructions to control the switch of the relay.
(2) Working mode 2 (mobile phone and ESP8266 module are mounted on the router at the same time)
①When the module is powered on, press the KEY key to switch to mode 2. The green light will change from off to on once every 1 second, indicating that it is waiting for the "EspTouch_Demo" APP to configure its WIFI account and password.
②At this time, connect the mobile phone to the router first, open the "EspTouch_Demo" APP, enter the router password, and click "Confirm"
③ Wait for the configuration to be successful. When the IP address of ESP8266 (such as 192.168.0.189) appears on the APP interface, it means that the ESP8266 module has successfully connected to the router and automatically memorized the account and password. It will automatically connect to Mode 2 next time.
It should be noted that the IP address 192.168.0.189 is dynamically assigned to the ESP8266 module by the router.
The address may change after the next reconnection,You can check the real-time IP address of the ESP8266 module in the router's device list.
④Open the "EasyTCP_20" APP, click "CONNECT", enter the IP address of the ESP8266 module: 192.168.0.189 and port number 8080, and then click "Connect"
After the connection is successful, the green light will flash slowly for 1 seconds and turn solid. Click the gray square to send instructions to control the switch of the relay.
