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.
