STEVAL-FKI868V1

The STEVAL-FKI868V1 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 main board is the NUCLEO-L152RE development board, equipped with a low power microcontroller STM32L to control the S2-LP and the ST-LINK/V2-1 debugger and programmer for firmware updating.
