WizFi220 (WiFi)
WizFi220 is a Wi-Fi module that provides the robust and stable Wi-Fi connectivity. WizFi220 performs all functions for Wi-Fi connectivity and TCP/IP processing. All you have to do is just sending commands to the module via serial interface.
WizFi220 is all compatible with WizFi210 in hardware & software, but it has the external power amplifier for the longer communication.
Description:
The WizFi220_CA is an ultra low power serial to WiFi module with power amplifier and on-board Chip Antenna. The module provides serial UART interface which enables connection to any embedded design utilizing and 8/16/32-bit micro-controller via simple commands. The module supports data rates up to 11 Mbps, and is compliant with 802.11b. The Serial to Wi-Fi embedded software allows devices and appliance manufacturers to easily add WiFi capabilities to their products with minor impact on the host micro-controller firmware. The WizFi220 provides all the hardware and software necessary to quickly set up a serial (UART) based link to a PC or external micro-controller.
