This miniature WLAN to RS232 module provides a cost effective, high performance Radio data link,
between devices over a WLAN network. The S103 is compliant with the 802.11b protocol standard and
can operate in Ad-Hoc or infrastructure mode, supporting 64/128-bits WEP security.
The modules are very simple to operate and offer low current consumption, allowing for extended battery
life when used in mobile applications. Data can be supplied directly to or from a microcontroller, thus
keeping the component count down and ensuring a low hardware cost.
