STEVAL-FKI433V1:Sub-1GHz transceiver development kit based on S2-LP (coming soon)

The STEVAL-FKI433V1 evaluation board is based on the S2-LP sub-1 GHz ultra-low power, low data-rate transceiver suitable for ISM bands and Wireless M-Bus.

The motherboard is the NUCLEO-L152RE board with STM32L low power microcontroller to control the S2-LP device and integrated ST-LINK/V2-1 debugger and programmer for firmware updating.

Key Features

  • S2-LP narrow band ultra-low power sub-1 GHz transceiver in a standalone RF Module tuned for 430 - 470 MHz frequency bands
  • STM32 Nucleo 64 development board with STM32L152RE MCU
  • Suitable for Wireless M-Bus systems
  • Associated S2-LP development kit including documentation, firmware for STM32L and GUI
