STMicroelectronics STEVAL-STWINWFV1

Overview

STEVAL-STWINWFV1 from STMicroelectronics is a Wi-Fi expansion board designed to add 2.4 GHz IEEE 802.11 b/g/n connectivity to the STEVAL-STWINKT1B and STEVAL-STWINKT1 SensorTile Wireless Industrial Node (STWIN) core boards via a dedicated 12-pin connector, powered by a single 3.3 V supply, and integrating the ISM43362-M3G-L44-E module with embedded TCP/IP stack and WPA2-PSK security for industrial IoT edge sensing applications.

For engineers reviewing the STEVAL-STWINWFV1 datasheet, STEVAL-STWINWFV1 pinout, STEVAL-STWINWFV1 application, or STEVAL-STWINWFV1 equivalent, key selection considerations include SPI interface compatibility (up to 25 MHz), regulatory certifications (FCC/CE/IC/ARIB), low-power Wi-Fi operation, secure authentication support, and mechanical integration with STWIN baseboards.

Technical Context

The STEVAL-STWINWFV1 functions as a plug-in wireless interface adapter-not a standalone IC-leveraging the ISM43362-M3G-L44-E module's integrated Broadcom MAC/baseband/radio and on-module TCP/IP stack. It communicates exclusively over SPI (SCK, MOSI, MISO, CS, DRDY, RST) and supports UART TX/RX via shared pins, with dedicated GPIOs for wake-up, boot control, and status signaling.

It operates at 3.3 V only, requires no external RF components or antenna tuning, and relies entirely on the host STWIN board for system-level processing, sensor fusion, and firmware execution. All regulatory compliance (FCC, CE, IC, ARIB) is satisfied at the module level, not the board level.

FAQ

Does STEVAL-STWINWFV1 require external antenna or RF matching components?

No. The ISM43362-M3G-L44-E module integrates a PCB trace antenna and all necessary RF front-end circuitry. No external antenna, balun, or matching network is needed - the board is fully functional upon connection to a compatible STWIN baseboard.

Can STEVAL-STWINWFV1 operate independently without STEVAL-STWINKT1B or STEVAL-STWINKT1?

No. It is an expansion board only - it has no MCU, no sensors, no power regulation beyond 3.3 V pass-through, and no standalone firmware. It must be mated with an STWIN core board to function as part of a complete industrial IoT node.

What firmware support is provided for STEVAL-STWINWFV1?

ST provides full driver integration in the STSW-STWINKT01 firmware package and the FP-IND-PREDMNT1 Predictive Maintenance Function Pack. These include Wi-Fi initialization, TCP/IP socket management, cloud connectivity examples (AWS IoT Core, Azure IoT Hub), and OTA update handling via SPI.

Is STEVAL-STWINWFV1 compatible with STM32CubeMX or STM32CubeIDE configuration tools?

No. It is not a microcontroller peripheral requiring HAL configuration. Its operation is managed through ST-provided middleware APIs (e.g., Wi-Fi middleware layer in STSW-STWINKT01). CubeMX/CubeIDE configure the host STM32 MCU - not the expansion board itself.
