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.
