A series of well-curated articles to understand the fundamental of electronics. The articles in this section elucidates basic concepts of electronics and design tips that can be equally useful to beginners and experts.
Sub-1 GHz radio links sit at the core of a wide range of products, including public safety radios, smart utility meters, RFID readers, and vehicle telematics units. Many of these systems now need to work across several regional frequency allocations without a hardware redesign for each market, while still running efficiently on battery power in a compact footprint. Qorvo's QPA9510 power…
We are all facing a huge transition in tech due to AI. In projects, we can run AI models on PCs, SBCs or even Cloud servers. In this tutorial, we are trying to see if we can run an AI model on a microcontroller board like the ESP32. To test this out, we are going to deploy and benchmark the 260K-parameter Tiny-LLM by Andrej Karpathy using his open-source llama2.c…
ROS 2 has become one of the most important technologies for engineers interested in robotics. But beginners often struggle with the same questions: Should I learn ROS 1 first? Do I need a physical robot? Which programming language should I know? And is ROS actually used in production?We discussed these questions with Shubham Nandi, co-founder and Chief Research…
ESP32 Cameras have become a popular choice for building low-cost wireless cameras, smart surveillance systems, and even small AI projects. But today, there are several options available, from the original ESP32-CAM to newer ESP32-S3-based camera boards and compact boards like the XIAO ESP32-S3 Sense. At first glance, they may look similar, but there are…
ESP32 development boards have been around for years, and we all have been doing a lot of projects with them. They come in various models, with different peripherals, and they perform different levels of tasks. If we are to check into a simple example, we have the normal ESP32 WROOM development boards as well as the same ESP32 with a camera sensor mounted onboard, the…
Playing smooth, full-motion video on low-power microcontrollers has been challenging due to memory and processing limitations. But with the dual-core speed, high SPI clock rates and an optimized decoding library on the ESP32, you can turn a simple development board into a working video player. If you want to create custom animations or add dynamic visual UI elements…
From June to July 2026, AI hardware demand affected more than just GPUs, CPUs, and high-bandwidth memory. TrendForce reported that DRAM contract prices would rise by 13%–18% in Q3 2026. NAND Flash contract prices would rise by 10%–15%. The main drivers are AI inference systems and large data center deployments.
The pressure also…
The Arduino UNO R3 is often the first board people use to learn electronics and programming. Connect an LED, read a sensor, control a motor, upload a sketch, and it can seem like you’ve already discovered everything the board can do.But there is much more going on underneath.At the heart of the UNO R3 is the ATmega328P microcontroller. That small chip contains hardware features that many…
We recently came across reports covered by news outlets about electric vehicles, specifically e-rickshaws, being remotely hacked and stalled in the middle of busy roads. The attackers were using Android apps, some of which were available on the Google Play Store under names like BAT-BMS, Epoch Li-on and Overkill Solar. These apps were apparently able to connect to some specific brands of the…
Modern server and data center design places increasing demands on the physical interconnect layer. At 112 Gbps and beyond, connectors are no longer treated as simple passive components; their design has a direct impact on crosstalk, impedance continuity, and mechanical integrity across the system. The following provides a technical overview of four Amphenol interconnect product families…
Bandwidth requirements in data centers, edge computing, and industrial automation are rising faster than the board space available to support them, and the equipment running these workloads often has to keep performing in conditions that are anything but gentle. That combination puts unusual strain on interconnects, which is precisely the segment TE Connectivity is targeting with its 56G…
