2 Getting started

This section describes the hardware requirements for the X-NUCLEO-

S2915A1 evaluation boards.

2.1 Overview

The X-NUCLEO-S2915A1 main features are:

• Based on S2-LP radio

• S2-LP narrow band ultra-low power sub-1 GHz transceiver tuned for

860 - 940 MHz frequency band

• Modulation schemes: 2-FSK, 2-GFSK05,2-GFSK1, 4-FSK, 4-GFSK05

• Air data rate from 0.1 to 500 kbps

• Ultra-low power consumption: 7 mA RX and 10 mA TX

• IEEE 802.15.4g hardware packet support with whitening, FEC, CRC

and dual SYNC word detection

• RX and TX 128 byte FIFO buffers

• Support to wireless M-Bus

• Excellent performance of receiver sensitivity (up to -130 dBm)

• Automatic acknowledgement, retransmission and timeout protocol

engine

• Compatible with STM32 Nucleo boards

• Compatible with Arduino UNO R3 connectors

• Support SMA antennas

• BALF-SPI2-01D3 IPD balun for matching network and harmonics

filter

• Sigfox compatible

• Sample firmware for P2P communication

• 6LoWPAN compatible thanks to STM32Cube

• RoHS compliant

The X-NUCLEO-S2915A1 expansion board can be used for the evaluation

of the S2-LP device in multiple applications.

The following demo samples are available for testing:

• wM-Bus demo

• Point-to-point communication protocol demo

• 6LoWPAN applications

• SigFox communication

You can develop other applications for evaluating the devices, such as:

• SigFox communication
