3 / 21 page DocID027622 Rev 2 3/21 UM1872 Description 21 1 Description The X-NUCLEO-IDS01A4 and X-NUCLEO-IDS01A5 boards contain the module SPSGRF- 868 or SPSGRF-915 based on SPIRIT1 low data rate, low power sub-1 GHz transceiver. The PCB layout is the same for both boards, with the only difference being the module used with it. 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) Table 1.
