Long-Range loT Connectivity is a Promise by LPWAN Evolution Board


The B-L072Z-LRWAN1 STM32 LoRa Discovery kit builds on the all-in-one open module from Murata that consolidates a STM32L072CZ microcontroller and Semtech SX1276 transceivers. The module lineaments a LoRa modem that implements ultra-long-range spread-spectrum communication and high interference immunity while reducing current expenditure. Since the module is open, developers have access to the STM32L072 MCU and its unit such as ADC, 16-bit timer, LP-UART, 12C, SPI AND USB 2.0 FS.

The B-L072Z-LRWAN1 kit combine an on-board debugger, a 64-pin STM32 Nucleo morpho connector, an Arduino-compatible connector, and a battery socket. It also comes with contact to a completely free improved ecosystem that adds the MDK-ARM Integrated Development Environment (IDE), STM32CubeMX configurator and software tools, and ST’s LoRaWAN protocol stack.The boards are based on the smallest and lowest-power LoRaWAN modules that exist on the market today, with a footprint not bigger than 13- x 12-mm and power desolating in the range of 1.2 µA in standby mode. The I-NUCLEO-LRWAN1 is an extention board for STM32 Nucleo or Arduino boards that can be simply plugged in to immediately starts work developing a full LoRa-based and/or FSK/OOK (Frequency-Shift Keying/On-Off Keying) function.

The board lineaments a LoRaWAN module from USI in sync with an STM32L052T8 MCU and Semtech SX1272 transceivers. The USI module comes pre-loaded with an AT command stack that helps streamline advancement and saves programming. The board is also assembled with ST’s LIS2DS12 3-axis accelerometer, LPS22HB MEMS pressure sensor, and HTS221 humidity-and-temperature sensor. Both boards are LoRaWAN-certified and fully manageable with wireless regulations, for example in the US, EU, Russia, India, and other countries using the 860-930 MHz recurrence bands. With two new ready to use prototype boards, STMicroelectrics objective is to cut the cost of evaluating LoRaWAN and other Low-Power Wide Area Network (LPWAN) technologies in addition to 6LoWPAN.
