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.
