This kit integrates the FCC-, RED- and ISED-certified WLR089U0 module and includes an on-board debugger, current measurement circuitry and extension headers to connect to additional boards. Supported by Microchip Studio Integrated Development Environment (IDE), software examples and a LoRaWAN stack, this development board greatly simplifies the development of LoRa technology end nodes.

The SAM R34 Xplained Pro is a hardware platform designed to evaluate the SAM R34 family of LoRa devices. This FCC-, ISED- and RED-certified board is not only an evaluation platform but also an excellent reference design for developing SAM R34-based LoRa end-node applications.

Microchip Studio is an Integrated Development Platform (IDP) for developing and debugging AVR^® and SAM microcontroller applications. It merges all of the great features and functionality of Atmel Studio into our well-supported portfolio of development tools to give you a seamless and easy-to-use environment for writing, building and debugging your applications written in C/C++ or assembly code.
