Prototype Boards Perform Cost-Effective,Ultra-Low-Power LPWAN Evaluation

February 17, 2017

Two ready-to-use prototype boards promise to cut costs for evaluating LoRaWAN and other Low-Power Wide Area Network (LPWAN) technologies including 6LoWPAN. Based on the smallest and lowest-power LoRaWAN modules on the current market, the boards feature a footprint not larger than 13 x 12mm and power consumption in the range of 1.2µA in standby mode.
• The B-L072Z-LRWAN1 STM32 LoRa® Discovery kit ($46.50) builds on the all-in-one open module from Murata® that integrates a STM32L072CZ microcontroller (MCU) and Semtech SX1276 transceivers. The module features a LoRa modem that provides ultra-long-range spread-spectrum communication and high interference immunity whilst minimizing current consumption.
• The B-L072Z-LRWAN1 kit includes an on-board debugger, a 64-pin STM32 Nucleo morpho connector, an Arduino-compatible connector, and a battery socket. It also comes with access to a completely free development ecosystem that includes the MDK-ARM Integrated Development Environment (IDE), STM32CubeMX configurator and software tools, and ST’s LoRaWAN protocol stack (I-CUBE-LRWAN).
