High sensitivity: down to -137 dBm Bullet-proof front end: IIP3 = -12.5 dBm Description 89 dB blocking immunity The STM32 Nucleo pack for LoRa technology Low RX current of 10 mA, 200 nA register and high-performance FSK/OOK RF transceiver retention modem (P-NUCLEO-LRWAN1) is a development Fully integrated synthesizer with a resolution of tool to learn and develop solutions based on 61 Hz LoRa and FSK/OOK technologies. FSK, GFSK, MSK, GMSK, LoRa and OOK This tool, in association with the certified modulations embedded software solution (I-CUBE-LRWAN), Built-in bit synchronizer for clock recovery provides the means to set up a complete LoRaWAN node compliant with class A, based Sync word recognition on the Semtech SX1272MB2xAS LoRa Preamble detection extension board. To control the LoRa extension 127 dB+ dynamic range RSSI board, the pack comes with a NUCLEO-L073RZ board based on the ultra-low-power, 32-bit Built-in temperature sensor and low-battery STM32L0 based on ARM Cortex -M0 indicator 1.65 V to 3.6 V power supply microcontroller. The I-CUBE-LRWAN is LoRaWAN class A certified. This pack is the perfect fit for any countries with 868 MHz or 915 ISM frequency bands.
