Battery Powered Smart Lock Reference Design With Cloud Connectivity Using SimpleLink™ Wi-Fi®

TIDC-01005

Design files

Overview

This reference design demonstrates how to create a battery-powered electronic smart lock with integrated Wi-Fi®. The design demonstrates how the SimpleLink™ Wi-Fi CC3220S wireless MCU (SoC) can be used as the main system controller and network processor to create a highly integrated design. TIDC-01005 reference design combines the CC3220S with a DRV8837 1.8A low voltage brushed DC motor driver to form the core of a Wi-Fi enabled electronic smart lock design. It also features the SimpleLink Bluetooth® low energy CC2640R2F wireless MCU to demonstrate Wi-Fi provisioning over BLE. The design leverages LaunchPad™ Development kits and the DRV8837EVM, which makes it easy to reproduce and evaluate. The software for TIDC-01005 is based on the SimpleLink SDK to enable maximum portability within the SimpleLink Platform.

Features

Direct Connection to Cloud from Smart Lock
Multiple Provisioning Methods (BLE Provisioning, Access Point Provisioning, and TI SmartConfig™)
Wide Range of Built-in Security Features
Over-the-Air (OTA) Software Update through the Cloud Using with Multiple Security Enablers
Motor Driver with Integrated FETs
Example Software Application Based on SimpleLink MCU Software Development Kit (SDK)
