The SPWF04 is a small cloud compatible Wi-Fi module that has been developed for IoT and M2M applications. This module provides advanced Internet-security and application protocols, and feature a microcontroller capable of supporting operation in standalone or serial-to-Wi-Fi modes Cloud-Compatible Wi-Fi Modules. The SPWF04 Wi-Fi module integrates an ARM® Cortex®-M4 STM32 microcontroller with a rich set of multi-functional GPIOs and with 2MB on-chip Flash and 256Kbyte 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. This module is FCC/CE/IC certified.
