Product Description:

We have another WIFI module in our shop. That WIFI module communicates via SPI interface, which is not easy for some beginners. But it might be a little hard to use this module. The code is long and complicate. Interpreting the code is always hard and boring, especially for those who don’t want to waste much time on this module.

So we supply another WIFI module here. It has UART interface. And it is more powerful, with more functions


TLG10UA03 is a new embedded Uart-Wifi modules supplied by elechouse.

Uart-Wif is an embedded module based on the Uart serial,according with the WiFi wireless WLAN standards, It accords with IEEE802.11 protocol stack and TCP / IP protocol stack,and it enables the data conversion between the user serial and the wireless network module. through the Uart-Wifi module, the traditional serial devices can easily access to the wireless network.

TLG10UA03 does a comprehensive hardware and software upgrades based on the products of the first two generations, now it’s more functional and more convenient to use,its main features include:

  • Support transparent transmission of serial completely,and achieve a plug and play serial
  • Support new AT+instruction set, Which is all based on ASCII format, it’s simple to use and pellucid.
  • Support more perfect TCP/IP protocol tack, support DHCP protocol for dynamicassignation of IP address and DNS domain name parsing.
  • Embed WEB server, and achieve the long-range parameters configuration through wireless network with IE browser.
  • Support more prefect transmission performance,the maximum sending rate can reach to 11KB/s.



  • 2*4 pins of Interface: HDR254M-2X4
  • The range of baud rate: 1200~ 115200bps
  • RTS/CTS Hardware flow control
  • Single 3.3V power supply


  • Support IEEE802.11b/g wireless standards
  • Support the range of frequency: 2.412~2.484 GHz
  • Support two types of wireless networks: Ad hoc and Infrastructure
  • Support multiple security authentication mechanisms: WEP64/WEP128/TKIP/CCMP(AES)WEP/WPA-PSK/WPA2-PSK
  • Support quick networking
  • Support wireless roam


  • Support multiple network protocols:
  • Support two types of work modes: auto and command
  • Support transparent transmission mode
  • Support AT+ instruction set
  • Support a variety of parameters configuration methods: serial/WEB server/wireless connection Application
  • Intelligent bus network, such as wireless credit card machine
  • Small financial payment network, such as wireless POS machine
  • Industrial equipment networking, such as wireless sensor things


Here we supply a detailed test example. You can download the test file in the Download list. With Arduino WiFi Module Shield, this wifi module can easily compatable with Arduino.

First you should configure the wifi module. On your PC you should visit the admin panel of your wifi network. Usually this address is

Connect wifi module with PC via USB-TTL module. Start wifi software to find the device. Input all the information needed to configure the wifi module.

Set the wifi IP address in server mode. Port is 8089.

After the configuration on wifi module, upload the following code to Arduino:

void setup()
void loop()
boolean currentLineIsBlank = true;
if (Serial.available()) {
char c = Serial.read();
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == 'n' && currentLineIsBlank) {
// send the webpage
Serial.println("HTTP/1.1 200 OKrnContent-Type: text/htmlrnrn<center><h1>Hello World!! I am WiFi WebServer!!!</h1></center>");

if (c == 'n') {
// you're starting a new line
currentLineIsBlank = true;
else if (c != 'r') {
// you've gotten a character on the current line
currentLineIsBlank = false;

Connect WiFi module with Arduino

In your browser, visit

We will explain configuration step by step in the test file. You can download below.
