I-NUCLEO-LRWAN1 USI® LoRa® expansion board for STM32 Nucleo Data brief Features • USI® low-cost, LPWAN module supporting LoRa® technology: – ST ultra-low-power STM32L052T8Y6 MCU, Cortex®-M0+ based with 64 Kbytes of Flash memory, 8 Kbytes of RAM, 2 Kbytes of EEPROM, T-RNG – Semtech SX1272 radio transceiver supporting LoRa®, FSK, GFSK, MSK, GMSK and OOK modulation – High sensitivity down to -137 dBm – 860 to 1020 MHz frequency range – 14 to 20 dBm output power – 2.0 to 3.6 V voltage range – -40°C to +85°C temperature range – Embedded 32 KHz and 32 MHz crystals – USART communication interface • ST accelerometer and magnetometer sensor (LSM303AGR) • ST relative humidity and temperature sensor (HTS221) • ST pressure sensor (LPS22HB) • Arduino™ connectors • SMA connector (antenna included in the kit) Description ® USI in partnership with STMicroelectronics developed the LoRa® expansion board for STM32 Nucleo (I-NUCLEO-LRWAN1). This board is an integrated solution allowing anyone to learn and develop solutions using LoRa® and/or FSK/OOK technologies. The I-NUCLEO-LRWAN1 features the USI® LoRaWAN™ technology module, addressing lowcost and low-power wide area network (LPWAN) which comes with embedded AT-commands stack pre-loaded. August 2017 1. Picture is not contractual. The I-NUCLEO-LRWAN1 can be controlled from an external host such as NUCLEO-L053 boards, running the I-CUBE-LRWAN embedded software. This software provides the means to set up a complete LoRaWAN™ node. The I-NUCLEO-LRWAN1 is LoRaWAN™ class A certified and sustains the class C. The I-NUCLEO-LRWAN1 includes the USI® LoRaWAN™ module, Arduino™ connectors, a SMA connector, a 50 Ω antenna and three ST environmental sensors. For more details about all the components of the LoRa®-Middleware library, refer to the STM32 LoRa® software expansion for STM32Cube user manual (UM2073).
