Mouser Electronics, Inc. distributes the SAM R34 LoRa Sub-GHz System-in-Package (SiP) family from Microchip Technology. The SAM R34 family of SiPs offers a 32-bit microcontroller, a software stack, and a sub-GHz LoRa® transceiver in a small 6 mm × 6 mm package.The Microchip SAM R34 sub-GHz LoRa SiPs, available from Mouser Electronics, incorporate a Microchip SAM L21 microcontroller based on a 32-bit Arm® Cortex®-M0+ core with up to 256 KB of flash memory and 40 KB of RAM. The built-in UHF transceiver supports LoRa and FSK modulation and covers frequencies from 137 MHz to 1020 MHz with a maximum transmit power of up to +20 dBm without external amplification. The SAM R34 family is compatible with Microchip's LoRaWAN protocol stack and supports Class A and Class C end devices, as well as proprietary point-to-point connections.
SiPs offer sleep modes as low as 790 nA, helping to extend battery life and conserve power consumption in smart devices. The SAM R34 SiP includes a USB interface, making it suitable for USB dongle applications or software updates via USB. SiPs are well-suited for a variety of battery-powered and sensor-based connected applications, including smart agriculture, smart city devices, and tracking devices for supply chain management.
Mouser also offers the SAM R34 Xplained Pro evaluation kit, powered by the Atmel Studio 7 integrated development platform. The kit includes reference designs and sample software that enable engineers to develop SAM R34-based LoRa end-node applications. The kit is certified by the Federal Communications Commission (FCC), Industry Canada (IC), and the Radio Equipment Directive (RED), ensuring that designs meet government requirements in all regions.
