Developers have had access for some time to MCUs that feature low-power operating states, shutting down peripherals and even the core itself to reduce system power requirements. For some applications, however, developers need more direct control over power utilization to ensure that portions of the system remain powered to meet key functional requirements. http://bit.ly/2qxcwtL
Designing an Internet-connected product requires many skillsets. Developers need to know how to write embedded software, build a circuit board, understand how to secure their device, and connect to a network to remotely update and manage their device. Building out the expertise and the infrastructure for a single IoT product can be challenging, time consuming, and expensive. Development teams require a way to jumpstart their development and minimize what they need to do in a typical design cycle in order to meet cost and time-to-market requirements. http://bit.ly/2qx4ktm
The antenna can contribute enormously to a system’s performance, but only if it is given due consideration early in the design process.
This article introduces popular antenna configurations such as the monopole and dipole, and discusses their performance characteristics and how to work with them in the real world. It also discusses newer antenna designs such as patch and chip antennas, and how they can help designers meet more demanding application requirements. http://bit.ly/2qwIMzJ
Digi-Key Feature Editor Murray Slovick describes HCL and introduces Infineon Technologies’ Arduino-compatible XMC1202 RGB LED Lighting Shield
As LED lighting systems mature, it is no longer sufficient to simply provide adequate brightness without glare. With research showing clearly that ambient light affects human biology, attention has now shifted to controlling the light source to affect human circadian rhythm, visual acuity, and even productivity. http://bit.ly/2pFy4nL
Digi-Key Editors Explain How To Take the Zero-Touch Approach to Securely Lock Down an IoT Device
The demonstrated ability of hackers to penetrate IoT devices says more about the level of security of these devices than the skill of the hackers: in most cases, the affected products lack the most basic security provisions. That said, basic security is simple conceptually, but its implementation requires careful attention at every node in a system to avoid vulnerabilities.
A pre-built security solution from Microchip Technology allows developers to implement zero-touch device provisioning in IoT applications built around the Amazon Web Services (AWS) IoT service. http://bit.ly/2pFnAVj
The architecture for an Industrial Internet of Things (IIoT) application uses a large number of networked sensors and actuators to monitor and control industrial processes. In the Industrial Internet Reference Architecture this collection of smart connected elements is called the Edge Tier, and a typical Edge Tier node is located on or close to the machine it serves. http://bit.ly/2qsA8Ch
The Internet of Things (IoT) holds the promise of high-resolution data which can be analyzed for energy monitoring
Where energy metrology was once largely confined to the interface between the power utility and the customer facility, organizations are looking for more detailed information from individual machines and pieces of equipment. http://bit.ly/2plSqov
IoT hardware and software need not be difficult
Bluetooth-enabled IoT devices provide ready access to data through smartphones and other gateway devices. Still, the design of low-power, battery-operated IoT solutions remains challenging in terms of both wireless sensing as well as optimization of power-draining communications subsystems. For designers with ever tightening time-to-market windows, the design task needs to be simplified.http://bit.ly/2pZ8QQ5
Significant upgrades to Bluetooth low energy introduced through versions 4.1, 4.2 and 5 were designed to make the short-range wireless standard a better choice for Internet of things (IoT) wireless applications. Part 1 of this two-part series describes those upgrades and outlines their advantages. Part 2, here, introduces Bluetooth low energy SoCs, modules and kits, and discusses their relative tradeoffs as a design approach. By the end of the series, a competent designer should be comfortable starting a Bluetooth low energy design. http://bit.ly/2plKmnI
This article by contributing editor Paul Pickering, details how the development of wearable health and fitness devices can be shortened using the Maxim Integrated MAXREFDES100#, a production-ready reference design.
The wearable health, wellness, and fitness market is extremely fast-moving, with new products appearing almost weekly. The availability of low-cost, low-power microcontrollers and widespread wireless connectivity have helped spur a drive towards portability and the growth of a new market in personal fitness monitors. http://bit.ly/2puM82B
