STMicroelectronics Intelligent Wi-Fi modules represent a plug and play and standalone 802.11 b/g/n solution for easy integration of wireless Internet connectivity features into existing or new products. Configured around a single-chip 802.11 transceiver with integrated PA and an STM32 32-bit microcontroller with an extensive GPIO suite, the modules also incorporate timing clocks and voltage regulators. The module is available either configured with an embedded micro 2.45 GHz ISM band antenna (SPWF01SA), or with an u.FL connector for external antenna connection (SPWF01SC). With low power consumption and small form factor, the modules are ideal for fixed and mobile wireless applications, as well as challenging battery-operated applications. The SPWF01SA.11 and SPWF01SC.11 parts are released with an integrated full featured TCP/IP protocol stack with added web server and additional application service capabilities. The SW package also includes an AT command layer interface for user-friendly access to the stack functionalities via the UART serial port.
