Product details

Overview

B-L072Z-LRWAN1 from STMicroelectronics is a LoRa®/Sigfox™-enabled Discovery kit built around the Murata CMWX1ZZABZ-091 open module, integrating an STM32L072CZ Arm® Cortex®-M0+ MCU (192 KB Flash, 20 KB RAM), SX1276 transceiver, and ST-LINK/V2-1 debugger. It supports LoRaWAN™ Class A/B/C and Sigfox™ RC1–RC4 protocols, operates in 860–930 MHz ISM band, and delivers +20 dBm RF output with -137 dBm sensitivity for LPWAN node development.

For engineers reviewing the B-L072Z-LRWAN1 datasheet, B-L072Z-LRWAN1 pinout, B-L072Z-LRWAN1 application, or B-L072Z-LRWAN1 equivalent, this board provides Arduino Uno V3 headers, USB OTG Micro-B, SMA/U.FL RF interfaces, 3×AAA battery support, and preloaded I-CUBE-LRWAN/X-CUBE-SFOX firmware examples for rapid prototyping of certified LPWAN endpoints.

Technical Context

The B-L072Z-LRWAN1 implements a complete LPWAN development platform where the embedded STM32L072CZ executes protocol stacks (LoRaWAN™, Sigfox™) while the SX1276 handles physical-layer modulation (LoRa®, FSK, GFSK, MSK, GMSK, OOK) with programmable bit rates up to 300 kbit/s and 157 dB link budget. Its open-module architecture exposes all MCU peripherals-USB 2.0 FS, 4-channel 12-bit ADC, dual DAC, LP-UART, I²C, SPI, and 6-bit timers-for full system-level customization.

On-board ST-LINK/V2-1 enables debug, programming, and virtual COM port communication over a single USB connection, while hardware features-including 7 LEDs, two push-buttons, 50-Ω SMA antenna, and dual RF connectors (SMA + U.FL)-support both lab validation and field-deployable prototype testing under real-world RF conditions.

FAQ

Does B-L072Z-LRWAN1 support over-the-air firmware updates?

Yes - the board supports OTA updates via LoRaWAN™ Class A downlink messages using the I-CUBE-LRWAN stack, which includes secure firmware update examples leveraging AES-128 encryption and CRC32 integrity checks. The STM32L072CZ's dual-bank Flash enables safe swap-based updates without bricking the device during transmission interruption.

Can the SX1276 transceiver be used independently of the STM32L072CZ MCU?

Yes - as an open module, CMWX1ZZABZ-091 exposes all SX1276 control lines (SPI, DIOx, RESET) and allows direct MCU-level access. Users may bypass the default LoRaWAN™ stack and implement custom PHY-layer drivers or proprietary protocols using the full register map and interrupt-driven DIO signaling documented in Semtech's SX1276 datasheet.

What IDEs are officially supported for B-L072Z-LRWAN1 firmware development?

ST officially supports Keil MDK-ARM (Windows), IAR EWARM (Windows), GCC-based toolchains (including STM32CubeIDE), and Arm Mbed OS (cloud and CLI). All include CMSIS-Pack support for STM32L072CZ device files, HAL drivers, and middleware stacks (I-CUBE-LRWAN/X-CUBE-SFOX) with verified build configurations and debug launch scripts.

Is the onboard antenna sufficient for regulatory certification testing?

No - the included 50-Ω SMA antenna is intended for functional evaluation only. For FCC/ETSI certification, users must replace it with a fully qualified, type-approved antenna matching the board's RF layout and grounding scheme, and perform conducted emission and radiated performance tests per EN 300 220-2 and FCC Part 15.247 requirements using calibrated test equipment.
