Hello, Welcome to the Altium Learning Hub

If you have experience working on PCB design teams, either in a single location or remotely, you've probably seen your share of successful and failed projects. Any project can fail or be severely delayed for a variety of reasons, and sometimes, the stars must align to ensure everything is delivered on time and under budget. Even after making many mistakes that caused project delays and fragmented team members, I'm still learning what it takes to...

Connector misalignment in multi-board systems tends to fly under the radar. Until it doesn’t. One subtle offset, one misaligned header, and suddenly you're dealing with bent pins, mechanical strain, or an assembly that just won’t go together. The result? Lost time, added cost, and unnecessary rework. What makes the difference is catching these issues early and designing with the whole system in mind. Altium makes that possible. With its unified...

One of the most popular AI at-the-edge platforms out there, the Jetson Orin Nano development kit provides a lot in such a small package. It has one of the highest performance-to-cost ratios among development kits and, as a result, has been sold out for months. If you can get your hands on one of these (which took me months to do) you’re in for a real treat. In this tutorial, we’re going to show you how to get started with the development kit...

Legacy bills of materials (BOMs) never truly disappear. For industries such as aerospace, medical devices, defense, and industrial automation—where products are built to last—supporting systems long after their initial release is essential. Legacy BOMs are revisited for servicing, compliance, or returning customer demand. Yet the original parts lists, often created years ago, rarely survive the test of time. Obsolescence, discontinued components...

FPGAs, DSPs, power amplifiers, MMICs… these components can have multiple voltage rails which require power sequencing in a specific order. The purpose of this sequencing is to prevent damage from latch-up, transients, ESD, and inrush current. Therefore, a sequencing process needs to be implemented in order to bring up power to the chip and instantiate the device’s embedded application. As FPGAs are large components with complex subsystems, power...

Integrated circuits (ICs) are integral to modern electronics, packing millions — or even billions — of components into a single chip. From consumer devices to aerospace systems, these microelectronic powerhouses handle everything from computation to signal processing with unmatched efficiency. But what exactly goes into a circuit, and how do the microscopic circuit elements in ICs work together to drive today's technology? This guide reviews the...

Training an AI model from scratch, even with existing datasets and help from friends, can be quite challenging. As we’ve seen in Understanding Neural Networks and Building Neural Networks on FPGAs, implementing the simplest embedded AI pipeline on hardware contains stumbling blocks every step of the way. In this article, we’re going to look at a relatively new platform that does all of the heavy lifting for us, leaving the AI training...

Simple systems often use switches to control power flow and power-up, assuming they use anything at all… Production-grade systems go further and include multiple circuits for transient protection, toggling and timing power regulators, and ensuring reverse polarity protection. One of the simplest yet most important portions of a power system with multiple rails is the power sequencer circuit, which toggles power to peripherals in a specific order...

Jira, originally designed for software development teams, has become a widely used tool for agile project management. While its default setup caters to software teams using frameworks like Scrum or Kanban, hardware development projects have unique challenges that require a different approach to consider hard constraints, long lead times, and dependencies across mechanical, electrical, firmware, and software disciplines. Despite these challenges...
