Kit includes

  • M03 module *1, 

  • 232 conversion board *1, 

  • 2 Db antenna *1, 

  • 5V/1A power *1.

  • HLK - WIFI - M03 is the third generation of sea LingKe electronics to launch a new embedded UART WIFI module products.

  • UART WIFI is wi-fi standard based on UART interface embedded module, built-in IEEE802.11 wireless network protocol stack and TCP/IP protocol stack, can realize conversion between user serial data to a wireless network. Through the UART WIFI module, traditional serial port devices can easily access the wireless network.

  • HLK - WIFI - M03 in the former two generations of products on the basis of comprehensive hardware and software upgrades, more powerful, more easy to use:

  • To fully support serial transparent data transmission mode and realize plug and play of the serial port

  • New AT + instruction set, all based on ASCII format, easy to understand, easier to use

  • More complete TCP/IP protocol stack, the dynamic IP address allocation support DHCP (dynamic host configuration protocol) and DNS domain name resolution capabilities

  • Built-in WEB server, realize the use IE browser through wireless network remote configuration module parameters

  • Higher transmission performance, up to 11 KB/S sending rate


  • interface
