3. Introduction

The IoT MSK is based on DA14585 (a SmartBond™ Bluetooth Low Energy SoC) and a number of motion and environmental sensors. The DA14585 SoC is offering a reduced boot time and supporting up to eight connections. It has a fully integrated radio transceiver and baseband processor for Bluetooth Low Energy. It can be used as a standalone application processor or as a data pump in hosted systems.

The IoT MSK board embeds a 2-Mbit QSPI Flash memory that can be used to store the downloaded software images over the SUOTA (Software Update Over The Air) profile and can also serve as storage for the second bootloader. Programming the IoT MSK is easy. There are two user manuals focusing on Software and Hardware details respectively.

Users can build a rich cloud application with the data from this IoT MSK in just a few steps. In addition, the cloud applications provided by Dialog can be used to monitor the data from the IoT MSK sensors and program IFTTT events.

Note

The key aspects of the hardware/software of the IoT MSK are explained in detail in this user manual. A Quick Start Guide is also available.
