STMicroelectronics Serial WiFi Module 2.4GHz SPWF01SA.21

The SPWF01SA and the SPWF01SC series of intelligent Wi-Fi modules embodies an affordable solution to plug and play and standalone 802.11 b/g/n devices, which enables easy integration of wireless Internet and IoT connectivity features into existing or new products.

The Modules are configured around a single-chip 802.11 transceiver with integrated PA and an STM32 32-bit microcontroller with an extensive GPIO suite that also contain timing clocks and voltage regulators.

With, low power consumption and small form factor, these modules are designed for both fixed and mobile wireless applications, this makes them ideal for home automation and security systems, wireless sensors, medical equipment, smart appliances and machine to machine communication.

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).
