X-NUCLEO-IDS01A4

UM1872 User manual Getting started with the Sub-1 GHz expansion board based on SPSGRF-868 and SPSGRF-915 modules for STM32 Nucleo Introduction The X-NUCLEO-IDS01A4 and X-NUCLEO-IDS01A5 are evaluation boards intended to provide a platform for testing the features and capabilities of the SPSGRF modules, based on the SPIRIT1 low data rate, low power sub-1 GHz transceiver device. These expansion boards can be plugged into the Arduino UNO R3 connectors of any STM32 Nucleo board. The user can mount ST Morpho connectors if required. Other expansion boards can easily be stacked to allow evaluation of different devices using sub-1 GHz communication. The boards are equipped with the following features: • On-board SPSGRF module based on the SPIRIT1 sub-1 GHz transceiver device • SPI EEPROM for saving parameters • LED for user interface • Jumper at 3V3 for checking the current consumption of the expansion board Figure 1.

The PCB layout is the same for both boards, with the only difference being the module used with it. Table 1. Expansion board details Evaluation board RF communication frequency X-NUCLEO-IDS01A4 868 MHz X-NUCLEO-IDS01A5 915 MHz Identification resistors Module used R14 mounted 868 MHz RF expansion board based on ETSI SPSGRF-868 certified module SPSGRF-868 for STM32 Nucleo R15 mounted 915 MHz RF expansion board based on FCC SPSGRF-915 and IC certified module SPSGRF-915 for STM32 Nucleo Description Identification of the RF communication frequency can be easily performed using the identification resistors (R14 or R15) mounted on the PCBs. Only 1 of the two resistors is mounted on the board to ensure quick identification. This information is also available in the PCB silk screen. Note that R14 and R15 are for identification purposes only, and changing these resistors does not change the RF frequency of the SPIRIT1 device. For information common to both boards, the nomenclature “X-NUCLEO-IDS01Ax” is used hereafter in this document. 1.1 Typical applications The evaluation boards can be used for evaluation of the SPIRIT1 device in multiple applications. The following demo examples are available for testing with the evaluation boards • wM-Bus: Wireless Metering Bus demo • Point-to-point communication protocol demo Please refer to the data brief for the firmware, available on www.st.com. Users can develop other applications for evaluating the devices. Some of these applications are: • Automatic meter reading • Home and building automation • WSN (wireless sensor network) DocID027622 Rev 2 3/21 21 Description UM1872 • Industrial monitoring and control • Wireless fire and security alarm systems 1.2 Abbreviations Table 2.

To function correctly, the X-NUCLEO-IDS01Ax must be connected to the STM32 Nucleo board as shown in Figure 2 below. The STM32 Nucleo firmware and related documentation is available on www.st.com at http://www.st.com/stm32nucleo Figure 2. X-NUCLEO-IDS01Ax plugged to STM32 Nucleo board The interconnection between the STM32 Nucleo and the X-NUCLEO-IDS01Ax has been designed to permit the use of any STM32 Nucleo board, although complete testing has been performed using the NUCLEO-L053R8 and NUCLEO-F401RE hosting the ultra-low power STM32. DocID027622 Rev 2 5/21 21 Getting started 2.2 UM1872 System requirements Using the Nucleo boards with the X-NUCLEO-IDS01Ax 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 Nucleo board to the PC Installation of the board firmware package and the wM-Bus graphical user interface utility on the user's PC requires the following: • 128 MB of RAM • Approximately 40 MB of hard disk space for the firmware • Approximately 15 MB of hard disk space for the wM-Bus GUI The use of the wM-Bus concentrator with the GUI requires additional boards to be connected to the PC. The GUI can be used to check the wM-Bus communication example. The Nucleo board acts as a meter and the STEVAL-IKR001Vx board connected to the PC acts as a concentrator. Please note that the wM-Bus example is valid only for X-NUCLEOIDS01A4 (868 MHz version). 2.3 Setting up the board Perform the following steps to set up the board: 6/21 1. Check that the jumper on the J1 connector is connected. This jumper provides the required voltage to the devices on the board 2. Connect the X-NUCLEO-IDS01Ax to the Nucleo board from the top, as shown in Figure 2. 3. Power the Nucleo board using the Mini-B USB cable 4. Program the firmware in the STM32 on the Nucleo board using the firmware example provided 5. Reset the MCU board using the reset button on the Nucleo board 6. The evaluation kit is ready for use DocID027622 Rev 2 UM1872 3 Hardware description Hardware description This section describes the X-NUCLEO-IDS01Ax features and provides information which could be useful to understand the board schematics.
