STM32WL3x

STM32 Nucleo-64 development board with STM32WL33CC MCU (868/915MHz)

mioty® Evaluation Stack for STM32WL3x

Unlock the full potential of the STM32WL3x SoC platform with the mioty Evaluation Stack. Designed to accelerate development of robust, ultra-low-power wireless applications, this stack is optimized for the Sub-GHz spectrum and fully supports the mioty® protocol, enabling reliable long-range communication for modern IoT use cases.

The STM32WL3x is an all-in-one ultra-low-power Sub-GHz wireless microcontroller that integrates one highly efficient multi-protocol radio (up to +20dBm transmit power and -132dBm sensitivity) plus one always-on wake-up receiver (~4µA) making it ideal for long-range, battery-friendly IoT design, more information here: www.st.com/stm32wl3
