Product Design Trends in 2020: Modular Hardware vs. Modular Software Product Design Trends in 2020: Modular Hardware vs. Modular Software Containerization is a core concept in modular hardware and modular software Modular hardware design is everywhere and has been on the rise in the embedded world. The drastic rise of the Arduino and Raspberry Pi ecosystems has encouraged greater use of a modular architecture. Open-source hardware platforms are gaining momentum, particularly in single board computer design and development board design. When it comes to modular software, we are Read Article
Adding a GNSS Module to Your SBC with Upverter Adding a GNSS Module to Your SBC with Upverter Adding GPS functionality to an embedded system is easier than you think Embedded systems for edge computing, autonomous systems, and other highly mobile systems need embedded navigation capabilities, but adding a GPS module to your next embedded system can be difficult. You’ll need to consider precise layout for GPS receivers in order to prevent signal degradation. There’s also the issue of compatibility with other global navigation satellite Read Article
Military-Grade Single Board Computer Design for UAVs Military-Grade Single Board Computer Design for UAVs A General Atomics MQ-9 Reaper, a hunter-killer surveillance UAV Unmanned aerial vehicles also known as UAVs, and colloquially known as drones, are aircraft designed to be piloted without a human on board. Drones are finding realistic uses outside the military, including applications in surveillance, agriculture, search and rescue, scientific studies, shipping, and many other areas. As tactical demands increase, so do the processing, memory, and Read Article
Building A Faraday Cage To Contain EMI, Part 2 Building A Faraday Cage To Contain EMI, Part 2 Part 1 of this article addressed the various ways in which EMI impacts products, and covered how to build a Faraday cage to contain it. This part of the article will focus on getting power into a product without letting EMI out; building a Faraday cage for rack-mounted products, determining whether or not logic ground should be connected to a Faraday cage while also providing some additional ways to build one. How to Get Power into a Product Read Article
Building a Faraday Cage To Contain EMI, Part 1 Building a Faraday Cage To Contain EMI, Part 1 EMI (Electromagnetic Interference) is a phenomenon that can plague a design if it is not properly and carefully addressed. One of the most often used but not necessarily thoroughly understood ways to contain EMI is through the use of a Faraday cage. This two-part article will provide an overview of EMI, how it can interfere with other products, and how to address EMI through the successful design and implementation of Faraday cages. Included in Read Article
DC Analysis of Linear and Nonlinear Circuits in Schematic Design DC Analysis of Linear and Nonlinear Circuits in Schematic Design These circuits can always use DC analysis If you’re working with a new design that involves some custom circuitry, it always helps to understand how the circuit behaves in DC. There is some merit to this, particularly if you are designing a custom power conditioning system, amplifier, equalizer, or other circuit. These circuits and many more require a range of analyses to evaluate their functionality, but the most fundamental of these is a DC Read Article
Why is There a Transmission Line Critical Length? Why is There a Transmission Line Critical Length? There is a little secret that most literature on PCB design will not tell you. Read & find out what you need to know about determining the transmission line critical length in your PCB interconnects. Read Article
Three Common PCB Design Mistakes You Can Spot in Your Gerbers Three Common PCB Design Mistakes You Can Spot in Your Gerbers Spotting some common PCB design mistakes will help get your board into production faster I’ll admit that I was not an excellent student until I hit graduate school. At that point, I started putting more energy into my homework than most other areas of my life. Sure, my social life became non-existent, but I soon became an exemplary student and I never looked back. Just like you need to do your homework while in school, you should do your homework Read Article
Pulsed Laser Diode Driver Circuit Layout for Lidar Pulsed Laser Diode Driver Circuit Layout for Lidar As part of the sensor suite for autonomous vehicles, lidar range maps play an important role in object identification in the surrounding environment, alongside car radar and other sensors or imaging systems. Building a functional driver circuit with small form factor and sleek packaging is critical for enabling lidar imaging/rangefinding around a self-driving vehicle. These same circuits can be adapted to other lidar applications, such as Read Article
