To function correctly, the X-NUCLEO-IDW01M1 must be plugged to the STM32 Nucleo board through the ST morpho or ARDUINO UNO R3 connectors as shown in the figure below. Information on STM32 Nucleo is available on ST website at http://www.st.com/stm32nucleo Figure 2: X-NUCLEO-IDW01M1 plugged with STM32 Nucleo board The interconnection between the STM32 Nucleo board and the X-NUCLEO-IDW01M1 is designed to work with any STM32 Nucleo board, even though complete testing was focused on the NUCLEO-L053R8 hosting the ultra-low power STM32L053R8T6, the NUCLEO-F401RE hosting the dynamic efficiency STM32F401RET6 and the NUCLEOF103RB hosting the Mainstream Performance line STM32F103RBT6. 6/20 DocID028608 Rev 1 UM1975 1.3 Getting Started System requirements Using the STM32 Nucleo boards with the X-NUCLEO-IDW01M1 expansion board requires the following software and hardware:   Windows PC (XP, Vista, 7, 8) to install the firmware package USB type A to Mini-B USB cable to connect the STM32 Nucleo board to the PC Installation of the board firmware package (order code: X-CUBE-WIFI1) and the Wi-Fi graphical user interface utility on the user PC requires the following:   128 MB of RAM 40 MB of hard disk space The X-CUBE-WIFI1 firmware and relative documentation are available on www.st.com 1.4 Setting up the board To set up the board: 1. 2. 3. 4. 5. 6. 7. Ensure that a jumper on the JP3 (position 1-2) connector is connected. This jumper provides the RESET signal to the SPWF01SA module on the board. Ensure that a jumper on the JP4 (position 1-2) connector is connected. This jumper provides the 2.5 V internal power supply to the GPIO6_ADC0 module signal. Plug the X-NUCLEO-IDW01M1 on the STM32 Nucleo board, as shown in Figure 2: "X-NUCLEO-IDW01M1 plugged with STM32 Nucleo board" Power the STM32 Nucleo board through the Mini-B USB cable Program the STM32 Nucleo board using the sample firmware provided Reset the STM32 Nucleo board MCU with the onboard Reset button The solution is ready to be used to evaluate Wi-Fi connectivity DocID028608 Rev 1 7/20 Hardware description 2 UM1975 Hardware description This section describes the X-NUCLEO-IDW01M1 features and provides useful information for understanding the board schematics. 2.1 X-NUCLEO-IDW01M1 expansion board for STM32 Nucleo The expansion board allows the user to test the functionality of the module. The SPWF01SA module embeds a low power Wi-Fi b/g/n transceiver SoC, SMD antenna and STM32 MCU. Board functionality can be manipulated through the firmware packaged with the X-CUBEWIFI1 software, which must be programmed on the STM32 Nucleo board microcontroller. Please, refer to user manuals UM1724 and UM1725 available on www.st.com for further information on STM32 Nucleo boards. The SPWF01SA module and the STM32 Nucleo board are connected through connectors CN7 (see Table 1: "Interconnection between STM32 Nucleo board and X-NUCLEOIDW01M1 (ST morpho connector - CN7)") and CN10 Table 2: "Interconnection between STM32 Nucleo board and X-NUCLEO-IDW01M1 (ST morpho connector - CN10)". Moreover, considering that signals available on CN5, CN6, CN8 and CN9 are also replicated on CN7 even and CN10 odd pin, it useful to indicate the indirect connection between STM32 Nucleo board and X-NUCLEO-IDW01M1 (see tables from Table 3: "Interconnection between STM32 Nucleo board and X-NUCLEO-IDW01M1 (Arduino UNO R3 Connector CN6 - Power)" to Table 6: "Interconnection between STM32 Nucleo board and X-NUCLEO-IDW01M1 through (Arduino UNO R3 Connectors CN9 - Digital)"). Pins marked with an asterisk (*) indicate an alternative pin for that specific function and pins marked with a hash (#) indicate a specific function reserved for future use and, not yet implemented on the module SPWF01SA.
