Smart Device Enablement Kit Developer's Guide

Introduction

This document describes the Wi-Fi Smart Device Enablement Kit development, which is supported by the
ATWINC15x0 Wi-Fi Network Controller (WINC) module that enables the developer to demonstrate the
functionalities of the ATWINC15x0 module for Internet of Things (IoT) applications.
This kit is pre-programmed with an application for demonstrating connectivity to the Microchip AWS
account with the help of an Amazon Alexa
to control the LEDs on the kit using cloud-based voice service virtual assistant such as Amazon Echo
®
Dot
. The mobile application is used for board registration, network configuration, and controlling and
monitoring the Wi-Fi Smart Device Enablement Kit.
For the demonstration shown in this document, the Wi-Fi Smart Device Enablement Kit is pre-configured
with the following:
• Customized MCU firmware
• AWS cloud configuration
• Alexa Skill setting
• Mobile application configuration
However, the developers can create and set up their own private AWS account, configure MCU firmware,
and build custom Alexa Skill with the help of this document.

Features

• ATWINC15x0, Qualified IEEE
• On-Board Host Microcontroller (SAML21G18B) for Easy Operation and Feature Demonstration
• On-Board CryptoAuthentication
• On-Board Li-Ion/Li-Po Charge Management Controller (MCP73833) for Lithium Battery Charging
• On-Board High Power Supply Rejection (PSRR) Low Dropout (LDO) Regulator (MIC5317)
