X-NUCLEO-IDW04A1 Hardware description

•The X-NUCLEO-IDW04A1 is aWi-Fi evaluation board

based on the SPWF04SA module, which expand the

STM32 Nucleo boards. The CE, IC and FCC certified

SPWF04SA module 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

SPWF04SA module communicates with the STM32 Nucleo

developer board host microcontroller though an USART

link. The SPI interface can also be used for the same

purpose.

Main Features

•The X-NUCLEO-IDW04A1 hosts FCC, IC and CE certified

SPWF04SAmodule (FCC ID: S9NSPWFS04, IC ID:

8976C-SPWFS04 and ETSI compliant)

•Compatible with STM32 Nucleo boards

•Equipped both with Arduino UNO R3 connectors and ST

morpho connector

•Scalable solution; it can cascade multiple boards for larger

systems

•Free development firmware library and examples,

compatible with STM32 Cube

Wi-Fi transciever Chip Antenna

Software overview 5

X-CUBE-WIFI1 software description

•X-CUBE-WIFI1 is an expansion software package

for STM32Cube. The software runs on STM32 and

it can be used for building Wi-Fi applications using

the SPWF01SA or SPWF04SAmodule. It is built

on top of STM32Cube software technology that

eases portability across different STM32

microcontrollers.

•It is compatible with the NUCLEO-L476RG and

the NUCLEO-F401RE when connected to one X-

NUCLEO-IDW04A1. The X-CUBE-WIFI1 software

comes with examples of implementation.

Key features

•Complete middleware to build applications using

the Wi-Fi module SPWF01SA or SPWF04SA

•Easy portability across different MCU families

thanks to the STM32Cube

•Easy to use abstract APIs to configure and use

SPWF01SA or SPWF04SA

•Sample applications that the developer can use to

start experimenting with the code

•Free, user-friendly license terms
