The ST STM32 LoRaWAN Discovery Kit is based on an all-in-one Murata Type ABZ open module solution to address low-power wide area networks (LPWAN) and support the LoRaWAN long-range wireless protocol. The Type ABZ module is powered by an STM32L072 ARM® Cortex®-M0+ microcontroller featuring 192 KBytes of flash, 20 KBytes of RAM, and 6 Kbytes of EEPROM. The STM32L0 ultra-low-power microcontroller offers low-power design features, targeting battery-powered and energy harvesting applications.
ST's I-NUCLEO-LRWAN1 STM32 LoRa extension board includes a LoRaWAN module powered by an STM32L052 microcontroller, an SMA connector, a 50-ohm antenna, and headers compatible with Arduino Uno R3 boards. The board also includes three ST environmental sensors: LSM303AGR accelerometer and magnetometer, HTS221 relative humidity and temperature sensor and LPS22HB pressure sensor.
Both the Discovery board and NUCLEO board come with LoRaWAN class A-certified I-CUBE-LRWAN embedded software that enables designers to set up a complete LoRaWAN node.
