Mouser now stocks the SAM R34 LoRa Sub-GHz SiP family from Microchip Technology. Providing industry-leading low-power performance for a wide range of IoT applications, the SAM R34 SiP family devices combine a 32-bit microcontroller, software stack, and sub-GHz LoRa transceiver in a small 6mm x 6mm package.

The SiPs include a Microchip SAM L21 microcontroller based on a 32-bit Arm Cortex-M0+ core with up to 256Kbytes of flash and 40Kbytes of RAM. The onboard UHF transceiver supports LoRa and FSK modulation and includes frequencies from 137MHz to 1020MHz with maximum transmit power up to +20dBm without external amplification. The device family is supported by the company's LoRaWAN protocol stack and supports Class A and Class C end devices, plus proprietary point-to-point connections.

The SiPs provide sleep modes as low as 790nA, serving to extend battery life and conserve power consumption in smart devices. The SiP incorporates a USB interface, making it ideal for USB dongle applications or for software updates via USB. The SiPs are fit for a variety of battery-powered and sensor-based connected applications, including smart city devices, smart agriculture, and tracking devices for supply chain management.

Mouser also stocks the SAM R34 Xplained Pro evaluation kit, backed by the Atmel Studio 7 integrated development platform. The kit comprises reference designs and software examples that allow engineers to produce SAM R34-based LoRa end-node applications. The kit is certified with the FCC, IC, and RED so designs can meet government demands across geographies.
