SPWF01SC.11

The SPWF01SC.11 from STMicroelectronics is a Wi-Fi module with integrated U.FL connector, 1.5MB of flash and Wi-Fi full stack. The intelligent Wi-Fi module represents 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 comprehensive power management subsystem and an STM32 microcontroller with an extensive GPIO suite, it also incorporates timing clocks and voltage regulators. It is integrated with full featured TCP/IP protocol stack with added web server and additional application service capabilities. For secure end to end communication with the cloud, an SSL/TLS stack is embedded in every module with no licensing charge. The SW package includes an AT command layer interface for user-friendly access to stack functionalities via UART serial port. It is possible to upgrade module firmware via UART and over the air.
