MCU STM32L072CZ Series for LoRa
STM offer LoRA and Sigfox with reference design demos available for customer development and all MP already.
Avnet Design Team provides full support for customers in LPWAN segment.
The STM32 Nucleo pack for LoRa®technology and high-performance FSK/OOK RF transceiver modem (P-NUCLEO-LRWAN1) is a development tool to learn and develop solutions based on LoRa®and FSK/OOK technologies.
This tool, in association with the certified embedded software solution (I-CUBE-LRWAN), provides the means to set up a complete LoRaWAN™node compliant with class A, based on the Semtech SX1272MB2xAS LoRa®extension board. To control the LoRa®extension board, the pack comes with a NUCLEO-L073RZ board based on the ultra-low-power, 32-bit STM32L0 based on ARM®Cortex®-M0 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.
