Microchip Technology SAM-IoT Wx v2 Hardware User's Manual

SAM IoT Wx v2 Hardware User Guide

Preface

Important: This document is applicable to the SAM-IoT WG v2 development board, which is
preconfigured to send data through the Google Cloud
board can be reconfigured to send data to different cloud service providers.
The SAM-IoT Wx v2 development board is a small and easily expandable demonstration and development platform
for IoT solutions, which is based on the SAM
board is designed to demonstrate the design of a typical IoT application which can be simplified by dividing the
problem into these blocks:
• Smart: Represented by the
• Secure: Represented by the
• Connected: Represented by the
The SAM-IoT Wx v2 development board features the following elements:
• The on-board debugger (nEDBG) supplies full programming and debugging support through MPLAB
It also provides access to a serial port interface (serial to USB bridge) and one logic analyzer channel (debug
GPIO).
• The on-board debugger enumerates on the PC as a mass storage interface device for easy drag-and-drop
programming, Wi-Fi configuration, and full access to the microcontroller application Command Line Interface
(CLI).
™
• A mikroBUS socket enables the user to expand the board capabilities with the selection from 1000+
sensor and actuator options offered by MikroElektronika (www.mikroe.com) through a growing portfolio of Click
™
boards .
• A light sensor is used to demonstrate the published data.
• Microchip MCP9808 high-accuracy temperature sensor used to demonstrate published data.
• Microchip MCP73871
• Microchip USB2422T
with PC using USB.
®
• MPLAB X IDE software to discover, configure, develop, program, and debug Microchip microcontrollers.
