Description

The X-NUCLEO-IDW01M1 is a Wi-Fi evaluation

board based on the SPWF01SA module, which

expands the STM32 Nucleo boards. The CE, IC

and FCC certified SPWF01SA 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

SPWF01SA module is also equipped with 1

MByte of external FLASH for firmware update

over-the-air (FOTA). The firmware features a

complete software IP stack to open up to 8

TCP/UDP sockets, as well as dynamic web

pages with SSI to interact with the module and a

REST API (get & post) for conveniently

transferring files to/from servers in the cloud. The

module can simultaneously behave as a socket

server and socket client. The firmware supports

secure sockets with TLS/SSL encryption,

ensuring secure end-to-end communications with

the cloud, with or without authentication. The

module operates as a client STA, IBSS, or

miniAP (with up to 5 client STAs). The X-

NUCLEO-IDW01M1 interfaces with the MCU on

the STM32 Nucleo board via the UART serial

port; the user can easily access the stack

functions using the AT command. X-NUCLEO-

IDW01M1 is compatible with both the ST morpho

and Arduino UNO R3 connector layout.

SG9011203).

1.2 Formal notices required by Industry Canada (IC)

English:

This device complies with Industry Canada license-exempt RSS standard(s). Operation is

subject to the following two conditions: (1) this device may not cause interference, and (2)

this device must accept any interference, including interference that may cause undesired

operation of the device.

French:

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils

radio exempts de licence. 'Exploitation est autorisée aux deux conditions suivantes : (1)

l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter

tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en

compromettre le fonctionnement.

The X-NUCLEO-IDW01M1 contains the IC certified SPWF01SA module (IC: 7420A-

SG9011203)

2.3 STM32 Nucleo connections

The X-NUCLEO-IDW01M1 expansion board is designed to be plugged directly on the

STM32 Nucleo board connectors. The X-NUCLEO-IDW01M1 is configured by default to be

compatible with the highest number of STM32 Nucleo boards possible. It may be also be

configured, via resistor placement, to use different I/O configurations in order to match

specific customer targets. Refer to the X-NUCLEO-IDW01M1 user manual for more

detailed information regarding the possible I/O configuration options.

Check to see if resistor R21 is present; if it is, please remove it as it may interfere with

JTAG debug.

2.4 EEPROM

The module has an embedded EEPROM used to host web pages and/or firmware over the

air (OTA) to remotely update the module firmware images.
