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)
