Introduction
Microchip's SAM R34 Xplained Pro Evaluation Kit is a hardware platform used to evaluate the
ATSAMR34 Low Power LoRa
Supported by the Atmel Studio integrated development platform, the kit provides easy access to the
features of the SAM R34 SiP and explains how to integrate the device in a custom design.
The Xplained Pro MCU series evaluation kits include an on-board Embedded Debugger, and no external
tools are necessary to program or debug the SAM R34 devices.
The Xplained Pro extension kits offer additional peripherals to extend the features of the board and ease
the development of custom designs.
