  • The STEVAL-FKI868V2 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-L053R8 motherboard is equipped with an STM32L0 low power microcontroller to control the S2-LP.

    The board integrates a ST-LINK/V2-1 debugger/programmer for firmware updating.

    Key Features

    • S2-LP narrow band ultra-low power sub-1GHz transceiver in a standalone RF Module tuned for 860-940 MHz frequency bands
    • STM32 Nucleo-64 development board with STM32L0 MCU
    • Suitable for Wireless M-Bus systems
    • Associated S2-LP development kit including, documentation, firmware for STM32L and GUI
    • Programmable RF output power up to +16 dBm
    • Modulation schemes: 2-FSK, 2-GFSK, 4-FSK, 4-GFSK, OOK, and ASK
    • Air data rate from 0.3 to 500 kbps
    • Ultra-low power consumption:
      • 6.7 mA RX
      • 10 mA TX @ +10 dBm
    • 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
