ST’s latest series of Wi-Fi modules offers a fast, flexible and affordable Plug&Play solution for integration of 802.11 b/g/n and TCP/IP technologies in IoT devices.

The modules integrate a complete TCP/IP stack and a user-friendly application layer that ensures a simple and effective way to use the modules via AT commands. The modules are configured around a single-chip 802.11 transceiver with integrated PA and an STM32 32-bit microcontroller with extensive GPIO support.  The modules also incorporate timing clocks and voltage regulators. Multiple antenna options are available.

With reduced power consumption and small form factor, the modules are ideal for both fixed and mobile wireless applications.

The modules are fully qualified and RoHS compliant.
