PRODUCT FEATURE
Global Alliance Technology Co., Ltd. 1.OnboardESP-01 WiFi modules and high performance microprocessor STM8S1032.Working ModeMode 1: mobile phone is directly mounted on WiFi moduleMode 2: mobile phones and WiFi modules are equipped on routersAdditional function: it can also be used as USB relay when ESP-01 is pulled out3.Transmission distanceIn an open environment, the maximum stable transmission distance is 100M when the mobile phone is mounted on the WiFi moduleWhen the WiFi module and mobile phone are carried on the router at the same time, the transmission distance depends on the signal strength of the router4.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 function5.onboard 5V, 10A//250V AC 10A//30V DC relay, which can be continuously pulled for 100 thousand times, has diode discharge protection, short response time6.Board mode selection and real time working status indicator7.Reserved UART debug interface and STM8 SWIM program download interface8.Board Size: 60*63mm


Relay control command (Hexadecimal) : Turn OFF the first relay:A0 01 00 A1Turn ON the first relay:A0 01 01 A2Turn OFF the second relay:A0 02 00 A2Turn ON the second relay:A0 02 01 A3Turn OFF the third relay:A0 03 00 A3Turn ON the third relay:A0 03 01 A4Turn OFF the fourth relay:A0 04 00 A4Turn ON the fourth relay:A0 04 01 A5
Configuration method:
Step 1: Connect DC 5V power supply at input terminal ‘IN+’and ‘IN-’which has marked on PCB.
Step 2: Install APP ‘EspTouch_Demo’on Android phone.User needs to configuration WIFI account number and password by MODE 2 at first time to use it.
Step 3: Install TCP transport tool APP ‘EasyTCP_20’on Android phone.It is used to send the relay control command, click ‘SWITCH’, and then press the gray square in the interface to input the name and content of the relay control command respectively (the command format is HEX).
Work Mode 1(Phone carry on WIFI module directly):
(1) It mean that the configuration is complete if green LED flashes cycle from 4 seconds slow down to 2 seconds after power on;
(2) The module sends a AP WIFI hotspot signal, which can be viewed in the WIFI network of the mobile phone, and then select the network.
(3) Open APP 'EasyTCP_20',click 'CONNECT',input IP address:192.168.4.1 and port number 8080.And then click 'Connect'.Green LED flashes cycle from 2 seconds to keep ON after the connection is successful.Click on the gray square to send an instruction to control the relay's switch.
Work Mode 2(Phone and WIFI module carry on router together):
(1) Short press S1 button to switch work mode to MODE 2 when green LED flashes cycle from 4 seconds slow down to 2 seconds after power on.And then blue LED turn ON.Green LED flashes cycle from 2 seconds faster to 0.5 seconds.It means that ESP8266 is waiting for the "EspTouch_Demo" APP to configure WIFI account number and password.
(2)Open APP lsquoEspTouch_Demorsquo and input router password and then click lsquo/confirm/irsquo.
(3)Wait for the configuration to succeed. When the IP address of the ESP8266 (such as 192.168.0.174) appears on the APP interface.It means that the ESP8266 module is successfully connected to the router, and the account and password are automatically remembered.The next time when user enter mode 2, it will automatically connect (about 20-60 second);
Note:rsquo192.168.0.174rsquo This IP address is dynamically assigned to the ESP8266 module by the router. The address may change after the next re-connection. User can view the real-time IP address of the ESP8266 module in the device list of the router.
(4)Open the "EasyTCP_20" APP, click "CONNECT", enter the IP address of the ESP8266 module: 192.168.0.174 and port number 8080, and then click "Connect". After the connection is successful, the green flashing from 2 seconds to keep ON.Click on the gray square to send an instruction to control the relay's switch.
Additional features(Used as USB Relay):
(1) Remove ESP8266 module.
(2) Prepare a USB to TTL converter by yourself and connect it to module.
(3) Select Mode 1 and open UART debugging software such as SSCOM32 after green LED flashing by each 2 second.
(4) Set Baud rate at 115200.Send control command in Hexadecimal to control relay.Our Services
