X-NUCLEO-IDW04A1

Wi-Fi 扩展板, SPWF04SA模块用于STM32 Nucleo, 集成SMD 天线

The from STMicroelectronics is an Wi-Fi expansion board based on SPWF04SA module and expands STM32 Nucleo portfolio. It has an embedded STM32 MCU, a low-power Wi-Fi b/g/n SoC with integrated power amplifier and power management and an SMD antenna. The module relies on 2MB MCU internal flash. 1MB of the internal flash is for storing user file system and to perform secure firmware update over the air. A hardware interface allows use of external memory to extend file system storage capability with no size limit. The firmware includes complete IP stack, dynamic web pages with SSI to interact with the module and a REST API for conveniently transferring files to and from servers in the cloud. It can simultaneously behave as a socket server and socket client. The firmware supports secure sockets with TLS encryption, ensuring secure end to end communications with the cloud. The X-NUCLEO-IDW04A1 interfaces with MCU on STM32 Nucleo board via UART serial port and SPI interface.
