STEVAL-IDW001V1
Wi-Fi daughterboard for STM32F0DISCOVERY
Data brief
Features
•Integrated SPWF01SA.11 Wi-Fi module
•Used as daughterboard for the
STM32F0DISCOVERY
•Can be used with the STEVAL- PCC0 18V1
UART to USB bridge board
•Integrated reset button
•Integrated power LED
•Dimensions: 53 mm x 65 mm
•RoHS compliant
Description
The STEVAL-IDW001V1 provides a platform for
evaluation of ST’s SPWF01SA.11 Wi-Fi module.
This product evaluation board integrates
connectors for use in conjunction with the
STM32F0DISCOVERY or with the STEVAL-
PCC018V1.
With the STM32F0DISCOVERY, it can be used
as a USB dongle on a PC to evaluate the AT
commands that are available in the Wi-Fi module
firmware. This can be done using a PC utility such
as HyperTerminal or similar.
When integrated with the STM32F0DISCOVERY,
the STEVAL-IDW001V1 allows the use of the Wi-
Fi module as a network co-processor for the
STM32F0 microcontroller. In this case it is
necessary to write an application for the
microcontroller to pilot the Wi-Fi module
capabilities.
