Product Overview

The X-NUCLEO-IDW04A1 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.
  • STM32 ARM Cortex® M4 with 256KB SRAM and 2MB flash memory
  • Integrated protocol stacks TCP/IP
  • Web server supporting dynamic web pages
  • Open, WEP, WPA2 Personal, WPA2 Enterprise Security, WPS for station
  • Firmware and FileSystem updates via UART and (secure) over the air (OTA)
  • 19 configurable GPIOs available, advanced low-power modes
  • Simple AT command set host interface through UART, or equivalent proprietary protocol over SPI
  • Embedded real-time microPython environment for customer applications and on-board development
  • Compatible with STM32 Nucleo boards, X-NUCLEO-IDW04A1 hosts FCC, IC, CE certified SPWF04SA module
  • Equipped both with Arduino® UNO R3 and (optional) ST morpho connector
