STMicroelectronics Discovery CMWX1ZZABZ-091 LoRa Development Kit for LoRaWAN 915 MHz B-L072Z-LRWAN1

STMicroelectronics B-L072Z-LRWAN1 Discovery LoRa Development Kit is a specialized communication and wireless development tool designed for LoRaWAN applications at 915 MHz frequency. This development kit integrates the CMWX1ZZABZ-091 module from Murata, which includes a high-performance SX1276 low-power transceiver supporting long-range modem capabilities and OOK/FSK modulation formats.

The embedded STM32L072CZY6 microcontroller manages transceiver operations, enabling efficient control and robust performance. This kit supports bi-directional communication for end devices operating in class A and class C protocols; it accommodates activation via Over-The-Air Activation (OTAA) and Activation-By-Personalization (ABP).

Output power is selectable between 14 dBm and +20 dBm, providing a maximum link budget of 157 dB. The module offers high sensitivity, capable of detecting signals as low as -137 dBm, with a programmable bit rate reaching 300 kbit/s. The fully integrated synthesizer features a resolution of 61 Hz, and the kit also incorporates mechanisms for sync word recognition and preamble detection, enhancing signal reliability.

The power supply flexibility allows operation through USB bus, external VIN/3.3V supply voltage, or standalone mode using 3 x AAA-type batteries. Connectivity options include SWD and USB 2.0 FS interfaces for programming and communication.

This development kit is suitable for wireless communication and embedded systems applications requiring ultra-low power use and long-range connectivity. It is widely applicable in industrial IoT, smart metering, and other environments demanding reliable LoRaWAN communication.
