STMicroelectronics – New STM32 board enables evaluation of LoRaWAN for long- range IoT connectivity


STMicroelectronics has released a development board which gives developers a ready-made platform for evaluating the LoRaWANTM Low- Power Wide-Area Networking (LPWAN) technology.

The B-L072Z-LRWAN1 STM32 LoRa® Discovery kit is based on an open LoRa module from Murata which includes an STM32L072CZ microcontroller and Semtech SX1276 transceivers.

The module’s spread-spectrum LoRa modem provides very long range and high interference immunity, and draws very little Transmit and Receive current.

Since the module is open, developers have access to the STM32L072CZ MCU and its peripherals, such as an ADC, a 16-bit timer, and low-power UART, I2C, SPI and Full-Speed USB2.0 interfaces. Designers can use ST’s STM32L0 hardware abstraction layer and embedded software libraries, and can extend the board’s functionality with STM32 Nucleo or ArduinoTM expansion boards.

The B-L072Z-LRWAN1 kit includes an on-board debugger, a 64-pin STM32 Nucleo morpho connector and an Arduino-compatible connector. It also comes with access to a free development ecosystem which includes the MDK-ARM integrated development environment, STM32CubeMX configurator and software tools, and ST’s I-CUBE-LRWAN LoRaWAN protocol stack.

The board is LoRaWAN-certified and fully compliant with wireless regulations in the US, EU, Russia, India, and other countries in which the 860-930MHz frequency bands are in use.
