Intelligent Wi-Fi modules from STMicroelectronics offer plug & play solution
The SPWF01SA and the SPWF01SC 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 and TCP/IP technologies in IoT devices.
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 modules are released with an integrated full featured TCP/IP protocol stack with added web server and additional application service capabilities and have a user-friendly application layer that ensures a simple and effective way to use the modules via AT commands.
Two different model options exist based on the amount of integrated Flash memory, the SPWF01Sx.2x orderable parts integrate 1.5 MB of Flash, while The SPWF01Sx.2x orderable parts integrate 512 kB of Flash. The modules are available either configured with an embedded micro 2.45 GHz ISM band ceramic antenna (SPWF01SA.xx), or with an u.FL connector to allow users to connect an external antenna (SPWF01SC.xx).
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.
Available models
SPWF01SA.11 - Integrated Ceramic Antenna and 1.5 MB Flash
SPWF01SC.11 - U.Fl. Antenna Connector and 1.5 MB Flash
SPWF01SA.21 - Integrated Ceramic Antenna and 512 kB Flash
SPWF01SC.21 - U.Fl Antenna Connector and 512 kB Flash
Evaluation tools
STEVAL-IDW01V1 - Based on the SPWF01SA.11, the board can be used as a dongle when integrated with the Daughter Board and is usable with STEVAL-PCC018V1 or as a Wi-Fi network coprocessor when integrated with the STM32F0-Discovery.
