  • The STEVAL-FKI915V1 evaluation board is based on the S2-LP sub-1GHz ultra-low power low data-rate transceiver suitable for ISM bands and wireless M-Bus.

    The NUCLEO-L152RE main board with an STM32L low power MCU controls the S2-LP and integrates the ST-LINK/V2-1 debugger and programmer for firmware updating.
    The STEVAL-FKI915V1 includes an external power amplifier from SkyWorks®, which allows the application to reach +27 dBm (500 mW) output power.

    Key Features

    • S2-LP narrow band ultra-low power Sub-1GHz transceiver in a standalone RF module tuned for 860-940 MHz frequency bands with external power amplifier
    • STM32 Nucleo-64 development board with STM32L152RE MCU
    • Suitable for wireless M-Bus systems
    • Suitable for SigFox applications
    • Associated S2-LP development kit including, documentation, firmware for STM32L and GUI
    • Programmable RF output power up to +27 dBm
    • Modulation schemes: 2-FSK, 2-GFSK, 4-FSK, 4-GFSK, OOK, and ASK
    • Air data rate from 0.3 to 500 kbps
    • Excellent performance of receiver sensitivity (up to -130 dBm)
    • Low duty cycle RX/TX operation mode
    • Automatic acknowledgement, retransmission and timeout protocol engine
    • SPI interface for microcontroller
    • USB interface
    • RoHS compliant
