The STEVAL-IKR002V3 development kit includes 2 RF daughterboards based on the SPIRIT1 low power, sub-GHz low data rate transceiver suitable for ISM bands and wireless M-BUS, and 2 motherboards based on the STM32L low power microcontroller to control the daughterboards.
Each motherboard features a USB connector for PC GUI interaction and firmware updates. A JTAG connector allows the development of specific firmware on the microcontroller.
