Accelerate Development of Remote IoT Nodes with the Industry’s Lowest-power LoRa® System-in-Package Family. With industry-leading low power consumption, the SAM R34/35 devices enable long-range wireless connectivity while extending system battery life.

LoRa® (Long Range) technology is extending the reach of the Internet of Things (IoT) by combining long-range wireless connectivity with lowpower performance. To accelerate the development of LoRa-based connected solutions, Microchip Technology Inc. introduced a highly integrated LoRa System-in-Package (SiP) family with an ultra-low-power 32-bit microcontroller (MCU), sub-GHz RF LoRa transceiver and software stack. The SAM R34/35 SiPs come with certified reference designs and proven interoperability with major LoRaWAN™ gateway and network providers, significantly simplifying the entire development process with hardware, software and support. The devices also provide the industry’s lowest power consumption in sleep modes, offering extended battery life in remote IoT nodes.
