The STEVAL-FKI433V2 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.
