802.11/b/g serial wifi Module

802.11/b/g serial wifi Module
Product Detailed
802.11/b/g serial wifi Module wifi antenna connector : IPX 802.11b/802.11g

       HLK-WIFI-M03 is the new third-generation embedded Uart-Wifi modules HLK-WIFI-M03 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.        HLK-WIFI-M03 does a comprehensive hardware and software upgrades based on the products of the first two generations ,nowit'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 dynamic assignation of IP address and DNS domain name parsing.       Support 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. CharacteristicInterface  2*4 pins of Interface:HDR254M-2X4  The range of baud rate:1200~ 115200bps  RTS / CTS Hardware flow control  single 3.3V power supplyWireless  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/WPA-PSK/WPA2-PSK/TKIP/CCMP(AES)  support quick networking  support wireless roam  Support directconnect with IPHONE and AndroidOthers  support multiple network protocols:TCP/UDP/ICMP/DHCP/DNS/HTTP  support two types of work modes:auto and command  Support transparent transmission mode  support AT+ instruction set  support a variety of parametersconfiguration methods:    serial/WEB server/wireless connectionApplication  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
