Extension board aids LoRa-based designs
The STM32 LoRaWAN Discovery Board from STMicroelectronics (ST) is now available at Mouser Electronics . The new Discovery Kit and I-NUCLEO-LRWAN1 STM32 LoRa Arduino-compatible extension board provides a development platform for learning and evaluating solutions based on LoRa and FSK/OOK radio frequency (RF) communication.
The 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.
The 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.
