3 W AC-DC Supply Offers 1.1” x 0.9” Form Factor

RECOM has introduced the RAC03-K which it claims is the smallest 3 W AC-DC power supply solution on the market. This converter can be used in a wide range of applications due to complete certifications for ITE and household standards. In a compact 1in² footprint, these modules deliver an output power of 3 W from -40°C to 60°C and 2 W up to 80°C. Despite such a high power density and small footprint, the RAC03-K series is a complete solution supporting Ecodesign Lot 6 standby mode operation for worldwide applications in automation, Industry 4.0, IoT, household and home automation.

With an input voltage range from 85 to 264 VAC and international safety certifications for industrial, domestic, ITE, and household applications, RECOM claims these are some of the most versatile power modules on the market. Due to their reinforced class II installation rating and their significantly wide margin to class B emissions compliance without external components, these are the easiest to use modular power solutions in the industry. Samples and OEM pricing are available from all authorized distributors or directly from RECOM.

TECHNOLOGY FOR SECURITY, SENSORS & THE IoT

Security Solutions for IoT
By Jeff Child
In this IoT era of connected devices, microcontrollers have begun taking on new roles and gaining new capabilities revolving around embedded security. MCUs are embedding ever-more sophisticated security features into their devices-both on their own and via partnerships with security specialists. Here, Circuit Cellar’s Editor-in-Chief, Jeff Child, looks at the latest technology and trends in MCU security.

Electromagnetic Fault Injection: A Closer Look
By Colin O’Flynn
Electromagnetic Fault Injection (EMFI) is a powerful method of inserting faults into embedded devices, but what does this give us? In this article, Colin dives into a little more detail of what sort of effects EMFI has on real devices, and expands upon a few previous articles to demonstrate some attacks on new devices.
 
Product Focus: IoT Gateways
By Jeff Child
IoT gateways are a smart choice to facilitate bidirectional communication between IoT field devices and the cloud. Gateways also provide local processing and storage capabilities for offline services as well as near real-time management and control of edge devices. This Product Focus section updates readers on these technology trends and provides a product gallery of representative IoT gateways.
 
Comparing Color Sensor ICs
By Kevin Jensen
Driven by demands from mobile phone, display and specialty lighting equipment manufacturers, the need for sophisticated and accurate chip-scale color and spectral sensors has become stronger than ever. In this article, ams’ Kevin Jensen describes the types of optical sensors and detectors. He also provides ideas on evaluating the suitability of each type for specific applications.

PC-BASED SOLUTIONS FOR EMBEDDED SYSTEMS
 
Mini-ITX, Pico-ITX and Nano-ITX Boards
By Jeff Child
Products based on the various small-sized versions of the ITX form factor—Mini-ITX, Pico-ITX and Nano—ITX-provide system developers with complete PC-functionality and advanced graphics. Circuit Cellar Chief Editor Jeff Child explores the latest technology trends and product developments in these three ITX architectures.
 
Using Small PCs in New Ways
By Wolfgang Matthes
Even simple MCU-based projects often require some sort of front panel interface. Traditionally such systems had to rely on LEDs and switches for such simple interfaces. These days however, you can buy small, inexpensive computing devices such as mini-PCs and notebook computers and adapt them to fill those interfacing roles. In this article, Wolfgang steps you through the options and issues involved in connecting such PC-based devices to an MCU-based environment.



FOCUS ON MICROCONTROLLERS
 
Guitar Game Uses PIC32 MCU
By Brian Dempsey, Katarina Martucci and Liam Patterson
Guitar Hero has been an extremely popular game for decades. Many college kids today who played it when they were kids still enjoy playing it today. These three Cornell students are just such fans. Learn how they used Microchip’s microcontroller and 12-bit DAC to craft their own version that lets them play any song they wish by using MIDI files.
 
Offloading Intelligence
By Jeff Bachiochi
While some embedded systems do just fine with a single microcontroller, there are situations when offloading some processing into a second processing unit, such as a second MCU, offers a lot of advantages. In this article, Jeff explores this question in the context of a robotic system project that uses Arduino and an external motor driver.
 
Building a Portable Game Console
By Juan Joel Albrecht and Leandro Dorta Duque
32-bit MCUs can do so much these days—even providing all the needed control functionality for a gaming console. Along just those lines, learn how these three Cornell students built a portable game console that combines a Microchip PIC32 MCU embedded in a custom-designed 3D-printed case, printed circuit board and in-house gameplay graphics. The device includes a 320 x 240 TFT color display.
 


… AND MORE FROM OUR EXPERT COLUMNISTS
 
Variable Frequency Drive Part 2
By Brian Millier
In Part 1 Brian started to describe the process he used to convert a 3-phase motor and OEM Variable Frequency Drive (VFD) controller—salvaged from his defunct clothes washer—into a variable speed drive for his bandsaw. In this article, he completes the discussion this tim,e covering the Cypress Semi PSoC5LP SoC he used, the software design and more.
 
Semiconductor Fundamentals Part 1
By George Novacek
Embedded systems—or even modern electronics in general—couldn’t exist without semiconductor technology. In this new article series, George delves into the fundamentals of semiconductors. In Part 1 George examines the math, chemistry and materials science that are fundamental to semiconductors with a look at the basic structures that make them work.
