Hello, Welcome to the Altium Learning Hub

In this article, we’re going to build a shield for an STMicroelectronics Nucleo development board, though as it is only using the Arduino compatible headers, it would be usable on any development board featuring Arduino-style headers. By prototyping on a development kit, we can prove our design without worrying about the implementation of the microcontroller, power, or communications. This also allows us to determine real-world processor...

In this multi-board project article, we’re continuing where we left off creating an Arduino-style shield for an STMicroelectronics Nucleo-64 evaluation board. In this project, everything is getting far more integrated, taking us closer to a finished product. We’re going to integrate the microcontroller onto our board and add batteries, charging power management, and wireless networking. In the process, we’ll talk about surface mount sub...

Transformers can provide very effective signal isolation and are used to manipulate AC voltage and current levels. They can achieve all this with a greater than 95% power efficiency, which is why we commonly see them used in bench power supplies, audio gear, computers, kitchen appliances, and wall-warts. Transformers used for 50/60 Hz power conversion have to be physically larger than those used in wall-warts, and hopefully, after reading this...

Just when you thought the chip shortage was rolling over, the supply chain rears its ugly head and US OEMs find themselves in another precarious position. As of 25 January 2022, the US Commerce Department released results from a survey stating that semiconductor inventories at OEMs are down to less than five days worth of inventory for key components, as reported in a release on the department's website and in other media outlets. Companies...

In the back half of 2021, it seemed like every news story proclaimed The Great Resignation was in full effect. Thanks to the pandemic, massively accelerated digital transformation, unprecedented stimulus, and the new focus on advanced technologies, people everywhere are changing jobs in search of new opportunities. Even beyond PCB design, embedded development, and hardware design in general, there are more ideas, jobs, and VC money than there...

You're done designing? Great! Now it's time to get your board fabricated.
