Getting started with X-NUCLEO-IDW01M1 Wi-Fi expansion
board based on SPWF01SA module for STM32 Nucleo
Introduction
This document provides detailed hardware requirements and board connections for the X-NUCLEO-
IDW01M1 Wi-Fi board based on SPWF01SA Serial-to-Wi-Fi Modules, to allow expansion of the STM32
Nucleo boards. The SPWF01SA module is FCC (FCC ID: VRA-SG9011203), IC certified (IC: 7420A-
SG9011203) and CE certified and includes an STM32 MCU, a low-power 2.4 GHz IEEE 802.11 b/g/n
transceiver with integrated power amplifier and power management, and an SMD antenna.
The X-NUCLEO-IDW01M1 can be plugged onto STM32 Nucleo boards thanks to the ST morpho and
Arduino™ UNO R3 connectors, and the same connectors allow different expansion boards to be easily
stacked on the X-NUCLEO-IDW01M1 board so you can evaluate Wi-Fi connectivity with different
devices in several applications.
The expansion board has the following features:
Onboard SPWF01SA module (order code: SPWF01SA.11) based on the STM32 MCU and a low
power Wi-Fi b/g/n transceiver SoC
USART configurable connections
Jumpers to obtain the SPWF01SA module RESET and I/O board signals (user software
dependent)
