Cloud-Compatible Wi-Fi Modules The SPWF04 Cloud-compatible Wi-Fi module from STMicroelectronics is set to accelerate development of all kinds of IoT and M2M devices. The module provides advanced Internet-security and application protocols, and features a microcontroller capable of supporting operation in standalone or serial-to-Wi-Fi modes.
The SPWF04 Wi-Fi module integrates an Arm® Cortex®-M4 STM32 microcontroller with a rich set of multi-functional GPIOs and with 2 MB on-chip Flash and 256 Kbyte RAM for generous code and data storage. Further extra features include a hardware cryptographic accelerator and an SPI port for faster host communications. In addition, the new MicroPython scripting engine dramatically simplifies development of custom applications to run directly on the module in standalone mode. Host interactions can use AT commands via a UART, compatible with the previous generation of Wi-Fi modules, or equivalent proprietary protocol over SPI.
