Description
The STEVAL-FKI433V2 evaluation board is based on the
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.
