The WLS1271L provides 2.4 GHz WLAN plus Bluetooth

functionality in an ultra-small module. The WLS1271L is

based on TI’s WL1271L SOC. The module features op-

timized RF performance including a high-efficiency RF

front end circuit. An integrated DC-DC converter allows

the module to operate from a single input voltage. The

module is designed to fit into small spaces, and requires

a minimum of external components to operate. Software

drivers are available for Linux, Android and WinCE oper-

ating systems.
